Category: IP Geolocation

If you’ve ever tried to make a critical decision based on IP intelligence — whether that’s targeting an ad, stopping fraud, enforcing content licensing, or investigating suspicious activity,  you already know one thing: IP data is only as valuable as your ability to interpret it correctly.

And increasingly, that’s becoming harder.

As the internet continues to evolve, IP addresses are no longer a clean one-to-one signal tied to a single user, device, or location. More and more often, multiple subscribers may appear to share a single public IP address, which can distort location accuracy, dilute risk signals, and complicate identity-based decisioning.

That’s why Digital Envoy introduced NAT Detector — a proprietary backend process within NetAcuity designed to identify NAT-enabled networks and shared-IP environments (including large-scale, carrier-grade deployments). NAT insights are processed and surfaced directly within our NetAcuity Connection Type database as a dedicated call-out: “nat” — giving teams critical context for more accurate, reliable decisioning in a shared-IP world.

Why shared IPs are becoming the norm

Network Address Translation (NAT) has been a foundational part of networking for decades. At its core, NAT allows multiple devices to share a single public IP address — a capability that’s extremely common in home, enterprise, and managed network environments.

But what’s changed dramatically in recent years is the scale.

As the global supply of IPv4 addresses has dwindled, many internet service providers (ISPs) and mobile carriers have accelerated their use of Carrier-Grade NAT (CGNAT) and other shared-IP strategies. In simple terms:   more users are being routed through fewer public IP addresses.

This approach helps networks stay operational,  but it also introduces new challenges for businesses that rely on IP intelligence for precision, trust, and enforcement.

The challenge: IP behavior is changing

For years, IP intelligence has served as a cornerstone signal across industries. But today, traditional assumptions about IP-based identification — such as uniqueness and stability — are becoming less reliable.

In high-value decisioning environments, that matters.

When many users share the same outward-facing IP address, it can lead to issues like:

• Reduced geolocation accuracy
• Inconsistent attribution and measurement
• Unstable device and identity signals
• False positives in fraud and cybersecurity systems
• Compliance and licensing friction for legitimate users    

Put simply: it’s not enough to know where an IP appears to be — you need to understand how it behaves.  

As Digital Envoy Chief Product Officer Vinod Kashyap puts it:

 “IP geolocation has evolved far beyond geolocating an IP address to a point on a map. With the growth of shared IP environments, and persistent IPv4 scarcity, understanding IP behavior is now a prerequisite for trustable insights.”

Smarter Decisions Start With NAT Insight

When NAT connection is in play, an IP address may represent multiple users, subscribers, or endpoints. NAT Detector helps surface that insight directly, so teams can:

• improve geolocation precision  
• better contextualize IP-level activity 
• make decisions based on more realistic IP assumptions  
• reduce reliance on fragile “one IP = one user” logic  

When NAT is detected, NetAcuity will explicitly identify the connection type as “nat,” making it easy to flag shared-IP environments in downstream workflows.

This matters because NAT doesn’t just affect location, it can impact the reliability of  every downstream signal  derived from IP data.

How NAT detection improves decisions across industries

NAT Detector isn’t limited to one market. It supports a wide range of use cases where IP intelligence plays a central role — especially when accuracy, trust, and performance are on the line.

Adtech & Marketing: more accurate targeting and measurement

In advertising and marketing environments, IP is often used for:

• audience segmentation
• regional targeting
• contextual decisioning
• measurement and modeling  

But if a public IP address is actually shared across many subscribers, it can inflate or distort assumptions about who’s behind a given signal.

With NAT Detector, teams gain clearer insight into when an IP address may not represent a precise geographic user  — improving targeting quality and helping reduce misinterpretation across campaigns.

Cybersecurity & Fraud Prevention: better risk context and fewer blind spots

Fraud and security teams often look at IP behavior as part of:

• risk scoring
• threat analysis 
• anomaly detection 
• enforcement decisions  

But shared infrastructure changes the picture. When traffic originates from NAT-enabled environments, traditional IP-level signals can become diluted.

NAT Detector helps strengthen decisioning by highlighting when traffic is tied to shared IP infrastructure, enabling more accurate risk interpretation and more resilient scoring. 

DRM & Content Licensing: stronger enforcement with fewer false flags

Streaming platforms, publishers, and content providers commonly use IP-based signals for:

• licensing enforcement
• regional restrictions
• compliance checks  

But NAT and CGNAT can create a mismatch between IP-based location and real end-user location, resulting in friction for legitimate viewers — or allowing unauthorized access to slip through.

NAT Detector helps teams identify potential discrepancies and make smarter enforcement decisions without over-relying on “IP location = user location” assumptions. 

Fintech & Compliance: sharper interpretation for high-stakes flows

In fintech and compliance environments, confidence is everything. Teams rely on IP intelligence to support:

• fraud prevention
• transaction risk analysis
• KYC / KYB workflows
• compliance validation  

When IP addresses represent shared NAT environments, behavior signals can become harder to interpret — especially in workflows built around uniqueness or consistency.

By identifying NAT-associated connections, NAT Detector supports more refined interpretation of IP address behavior, improving outcomes in both fraud detection and compliance decisioning. 

A more realistic foundation for modern IP intelligence Insights

The shift toward shared IP address environments isn’t a temporary trend — it’s a structural change driven by real-world pressures like IPv4 scarcity and expanding global connectivity.

That means the future of IP intelligence will be defined not only by “where” an IP appears to be, but also   what it represents   in today’s network conditions.

NAT Detector helps address that reality — delivering a more accurate foundation for teams that need dependable IP-based decisioning at scale.

When it comes to IP address geolocation, the numerous use cases that our customers employ require data to be parsed in many different ways. We often find ourselves playing a game of geographical Goldilocks, looking for the level of IP granularity that is not too big, not too small, but juuuuuust right.

Here are some examples of how challenges with city-level precision in the NetAcuity Pulse IP geolocation database can translate into real-world operational and user-experience issues:

• Giving website visitors a drop-down of city names to choose from, and the NetAcuity database returns an overly long list
• IP to city-level targeting where the city response is too granular for practical market-level use
• Using NetAcuity for Flat File deployments where there are too many rows or IP ranges to ingest due to city-level IP range fragmentation

Based on scenarios like this, Digital Element set out to solve this challenge. To do so, our team mapped small cities and suburbs around the world to the larger metropolitan areas that they fall within. This enables Digital Element customers to target major metropolitan areas without having to identify and manually select every surrounding suburb or neighborhood.

As outlined in our blog The Tricky Science Behind IP GeolocationIP address density in a major city often fails to reflect the true population of its surrounding metropolitan area, particularly when addresses are correctly assigned to nearby suburbs.

Small City Mapping

To meet the needs of our customers’ wide range of use cases and reduce operational complexity, Digital Element introduced Small City Mapping. This capability allows customers to convert an existing “small city” response from the Pulse city field into its associated larger metropolitan city, saving time, simplifying logic, and improving usability.

To demonstrate how this works, let’s use India as our geographic example and apply it to a common use case mentioned above: reducing overly long city selection lists.

Imagine you’re on the web development team for the IKEA India website, building a store locator for visitors. IKEA typically operates stores in major metropolitan areas, so visitors from surrounding cities need to be mapped accurately to the nearest metro where a store exists.

One of India’s 28 regions, Maharashtra (MH), contains approximately 350 cities. Asking users to manually scroll through hundreds of city options creates unnecessary friction.

Using Small City Mapping, visitors whose IP addresses fall within smaller surrounding cities are automatically associated with the closest major metropolitan area, ensuring relevant store locations are displayed instantly.

Here is an example of IP address traffic observed on the IKEA website.

The web development team can query these addresses against the NetAcuity database to determine the Region, City, and City Code associated with these IP addresses. Below is what NetAcuity will return.

The cities associated with the IP addresses from web traffic were Andheri, Bandra West, and Dharavi. The web development team can then use the Small City Mapping decode file To determine what big cities these three smaller cities map to.

As you can see, the IP address ranges all map to Mumbai as the big city. Because these small cities all map to Mumbai, logic can then be built into the website to ensure that visitors from any of the IP ranges that correspond with these cities are shown the Mumbai stores when using the store locator tool.

In any cases where IP address ranges are consecutive, the rows will be consolidated.

Small City Mapping decode result:

How This Enables Modern, Cookieless Use Cases

A/B testing content by market using IP context
Small City Mapping allows teams to test messaging, layouts, or offers at the metro level instead of fragmented city responses. This produces cleaner experiments, more reliable attribution, and consistent market definitions without relying on cookies or logged-in users.

Cookieless geo-targeting with trustworthy measurement
Because NetAcuity uses authoritative IP intelligence rather than user-declared location, organizations can localize experiences while maintaining consistent, privacy-forward measurement, especially critical as third-party cookies continue to disappear.

Minimizing false blocks in live sports streaming
Overly granular or misaligned city-level targeting can lead to accidental content blocks. By mapping suburbs and small cities to their correct metro areas, Small City Mapping helps streaming platforms enforce regional rights accurately while reducing false positives that frustrate legitimate viewers.

How to Access the Small City Mapping Decode File

The Small City Mapping Decode File is available to all Digital Element customers at no additional cost and can be accessed in the following ways:

• Downloadable via the Digital Element support portal on the Decode Files page as a .tab or .csv file
• Loadable into a local database and usable across NetAcuity deployment options, including Server/API, Flat File, Embedded API, and Cloud Service
• Customers using NetAcuity Server/API, Flat File, or Cloud Service can query or dump Feature Code 93 (Decode DB) and Feature Code 26 (Pulse) to automatically populate big-city mappings

Feature Code 93 mirrors the fields in the Small City Mapping Decode File and can be licensed through the Client Success team.

In the coming months, we will be introducing Feature Code 93 which will enable DE customers to make a single query or create a flat file where there is a dedicated field to the existing “pulse-city” and the “decode-big-city”. This new Feature Code will produce an industry-first data set that returns two locations for a single IP address: the small city that the IP address is located, and the larger metropolitan city that it is associated with.

Frequently Asked Questions About Balancing IP Precision with User Needs

How can I A/B test content by market using only IP context?

By using NetAcuity IP geolocation with Small City Mapping, teams can group users into consistent metropolitan markets based on IP address alone. This enables clean A/B testing across defined regions without cookies, logins, or self-reported location data.

Can Digital Element support cookieless geo-targeting?

Yes. Digital Element’s IP-based geolocation enables location-aware content delivery and measurement without relying on cookies. This supports privacy-forward targeting while maintaining reliable geographic attribution.

How does Digital Element reduce false blocks in geo-restricted live streams?

Small City Mapping ensures that IP addresses in surrounding suburbs are accurately associated with the correct metropolitan area. This reduces accidental blocks caused by overly granular city-level enforcement while still respecting regional content rights.

What level of IP granularity does NetAcuity support?

NetAcuity supports country, region, metro, city and postcode y-level targeting, globally. Small City Mapping adds flexibility by allowing customers to operate at the most appropriate geographic level for each use case.

When evaluating an IP geolocation service, it’s important to look beyond surface-level claims and focus on the factors that matter most for your specific business and use case.

While many vendors offer some form of IP geolocation data, there are meaningful differences in how that data is sourced, validated, updated, and delivered. Those differences can directly impact accuracy, scalability, and long-term performance.

In this guide, we’ll walk through what to look for in an IP geolocation service while covering accuracy, data freshness, coverage, and real-world applicability, so you can make an informed decision and understand how Digital Element approaches IP-based location intelligence.

What is IP Geolocation and Why Does it Matter?

IP geolocation refers to identifying the physical location of a device connected to the internet using its IP address. Businesses can use this information for various applications, such as improving user experience, personalizing content, managing digital rights, detecting fraudulent activities, and targeting marketing campaigns.

IP geolocation is helpful for businesses that operate online and need to provide location-based services or track the location of their website visitors.

What to look for in an IP geolocation service

With so many options available, how do you choose the best IP geolocation database for your business? Read on to dive deeper into these factors and provide actionable tips to help you make an informed decision.

1. Trusted Brand Reputation

Perhaps the most important part of selecting any vendor for your business, it’s critical to start by ensuring the IP geolocation service provider has a proven track record of success and a reputation for providing high quality data, reliable service, and exemplary customer support. This is bigger than simply ensuring your business gets results — your own reputation is also at stake. 

Ask vendors for a client list, examples of tangible results, and any awards recognizing their superior technology and solutions.

2. Accuracy of Data Beyond Country and Region

Data accuracy is one of the essential features to consider when selecting an IP geolocation service provider. Accuracy varies widely among vendors, and depends on several factors, such as the number of data sources, the frequency of updates, and the methodology used to collect and analyze the data. The data’s accuracy and reliability directly affects the service’s usefulness for your business.

Country-level accuracy is generally 95-99.99% for most IP geolocation vendors, whereas city-level accuracy can range from 40-97%. Poor accuracy results in off-target ads and content, or might allow unauthorized access to digital content and services.

You want an IP geolocation service that can provide up-to-date and precise geolocation data, such as real-time ISP and ASN lookup, IPv4 and IPv6 data, and time zone and postal/ZIP code information. 

Look for an IP geolocation service with a reputation for providing the most accurate data, which can positively impact your business.

Beyond merely accepting accuracy at face value, it’s important to choose a vendor that can verify its data accuracy with independent review from third-party auditors. This assesses the data itself and the methods used to collect it, and is a great way to prove that a vendor can “put its money where its mouth is.”

3. City-Level and ZIP-Code Granularity at Scale

Ask yourself: How hyperlocal is the data within my target geographies? Do you return postcode-level geography? If so, do you default to city-center postcodes?

If highly granular city or postcode-level data is important to your business, then it is important to understand that most vendors do not perform well (or at all) at this level. Most either aggregate traffic into large metropolitan areas and/or provide city-center default postcodes which may be 10 or even 100 miles away from web visitors’ actual locations. 

ZIP+4 data is especially beneficial to marketers who want to target very specific audiences concentrated in more pinpointed locations within the United States.

4. Data Freshness and Update Frequency

IP geolocation provides various features and functionalities that enable you to get accurate geographical information about an IP address. The API returns essential details such as the country, region, city, postal code, time zone, ISP, and ASN of the IP address. 

Additionally, it provides endpoint URLs to retrieve the country flag, calling code, and other essential information such as proxy and VPN details.

One of the fundamental features of IP geolocation is its ability to provide location-based information, which can be used for ad targeting, content personalization, online fraud detection, and digital rights management.

Most IP geolocation vendors simply repackage publically available (free) Whois registration data, and some supplement with user-supplied data. Simple Whois information and/or user-supplied data, however, are not reliable methods for accurate geolocation when used in isolation.

If accuracy, coverage, and granularity are important to your business, select a vendor that employs multiple methodologies, including network infrastructure analysis and user-validated location feedback, as well as has a team of data analysts that double checks automated data collection methods and runs quality-assurance checks.

5. IP Coverage and Global Reach

Ask yourself: Besides IP geolocation information, what other datasets do they offer?

Information such as proxy or VPN type; mobile carrier; connection type/speed; home/business user; industry classifications; longitude/latitude; time zone; domain name; ISP; company name; organization name; demographics; and more can be impactful datasets for creating more meaningful user experiences.

6. Ease of Geolocation Integration

Ease of integration is another crucial factor when choosing an IP geolocation service. 

You want an API that can be quickly and seamlessly integrated into your existing systems, such as your website, mobile app, or CRM. Look for an IP geolocation API with various integration options, such as REST API, JSON, XML, and CSV.  Some IP geolocation services also offer SDKs and client libraries for popular programming languages like JavaScript.

Integration is a massive compliment to accuracy, especially for things such as urban planning and placing locational services. The easier it is to integrate the IP geolocation service, the faster you can start taking advantage of the benefits it provides.

7. Product Pricing

The pricing model of IP geolocation varies from one service provider to another. While some IP geolocation providers offer a free plan, others require a subscription plan. Pricing depends on various factors, such as the number of API calls, the level of accuracy and precision required, the level of support, and the number of features needed.

Some IP geolocation service providers have a pay-as-you-go pricing model, while others require an annual or monthly subscription. Some providers offer discounts for bulk purchases or special pricing for non-profit organizations or educational institutions.

When selecting an IP geolocation service provider, it is necessary to consider the pricing model and ensure that it is within your budget. Consider the API’s response time, uptime, and latency to provide a smooth user experience.

IP Geolocation vs. GPS: Understanding Accuracy at Scale

When teams evaluate location data for advertising or personalization, IP geolocation is often compared directly to device‑based GPS. While both serve important roles, they’re designed for very different use cases.

GPS data delivers extremely precise, real‑world positioning, often down to a few meters. However, that level of accuracy comes with limitations: it requires explicit user permission, is restricted by mobile operating systems, and doesn’t scale easily across all devices, browsers, and environments.

IP geolocation, on the other hand, is built for scale. It allows businesses to understand where users are connecting from without relying on app‑level permissions or device sensors. For ad delivery, streaming, ecommerce personalization, and fraud prevention, IP geolocation offers a practical balance of accuracy, reach, and privacy compliance.

Rather than replacing GPS, IP geolocation complements it by enabling consistent location intelligence across desktop, mobile web, CTV, and server‑side environments where GPS simply isn’t available.

Frequently Asked Questions About IP Geolocation for Businesses

How accurate is IP geolocation in general?

High-quality IP geolocation data can reliably identify a user’s country, region, and city, and in many cases supports ZIP-code or postal-level targeting. Accuracy depends on factors such as data sources, validation methods, IP coverage, and how frequently the data is updated.

For most digital use cases, IP geolocation provides a strong balance of precision, scale, and reliability.

How does IP geolocation compare to device GPS for advertising use cases?

Device GPS can provide very precise real-world location data, but it requires explicit user permission and is limited to environments where GPS access is available. That makes it difficult to scale across all advertising channels.

IP geolocation is designed for scale. It works across desktop, mobile web, connected TV, and server-side environments without relying on device-level permissions. While it doesn’t offer meter-level precision, it supports consistent city- and ZIP-level targeting, which is often more practical for large-scale ad delivery and personalization.

Why does data freshness matter for IP geolocation?

IP addresses and network assignments change frequently as internet infrastructure evolves. If geolocation data isn’t updated regularly, accuracy can degrade over time, especially at the city and ZIP-code level.

Frequent updates help ensure location mappings reflect how users are actually connecting to the internet, rather than relying on outdated assumptions.

How can ecommerce teams evaluate the freshness of IP geolocation data week to week?

Ecommerce teams often look at update frequency as a key indicator of data quality. Weekly updates are generally considered best practice, as they help capture changes in IP usage patterns and reduce the risk of mis-targeted traffic.

Fresher data supports better regional personalization, more accurate analytics, and improved performance for time-sensitive campaigns like promotions or seasonal sales.

How does Digital Element’s NetAcuity data compare to other IP geolocation providers?

Most leading providers deliver strong accuracy at the country level, but differences become more apparent at finer levels of granularity and at scale. NetAcuity is designed to support consistent city-level and ZIP-code targeting across large global audiences, which is particularly important for programmatic and connected TV advertising.

When comparing providers, teams often look beyond headline accuracy claims to factors like update cadence, IP coverage, and consistency across markets.

Is IP geolocation suitable for connected TV and programmatic advertising?

Yes. IP geolocation is widely used for CTV and programmatic advertising because it works across devices, doesn’t require user opt-in, and supports geographic targeting at scale. This makes it well suited for streaming and household-level environments where GPS data isn’t available.

IP geolocation is a subject that is often misunderstood.

Generally, people understand that it involves mapping IP addresses of internet-connected devices to a geographic location, but the nuances behind accuracy, coverage, granularity, and validation can be confusing.

In IP geolocation, validation refers to cross-checking inferred IP location against real-world observational signals to assess confidence and correct location assignments over time.

In this post, we break down the science behind IP geolocation accuracy, explain how validated observations improve confidence at the city and postal code level, and demonstrate why bi-directional accuracy matters for teams that rely on location data to perform at scale.

Why City-Level Accuracy Matters in IP Targeting

Let’s say you’re a marketer targeting Atlanta, Georgia for a programmatic or CTV campaign. Are you trying to reach only Atlanta proper, or the broader Atlanta metropolitan area, including suburbs where the majority of the population actually resides?

In most real-world use cases, success depends on the latter, because population density rarely aligns with city limits alone. As urban sprawl continues to reshape how people distribute themselves geographically, effective city-level targeting must account for surrounding suburbs and metro areas where the majority of audiences actually live.

Accurate IP geolocation must work in both directions by assigning IPs to where users actually live, not just to city centers, and by accurately reflecting real population distribution across entire metropolitan areas.

Digital Element has invested heavily in technology that supports this type of bi-directional IP accuracy, helping marketers avoid over- or under-targeting when defining geographic boundaries.

When More IP Addresses Actually Mean Less Accuracy

Returning to the Atlanta example:

• Digital Element may return 5.8 million IP addresses mapped to the Atlanta market
• Another provider may return 6.5 million IP addresses for the same area

At first glance, the larger dataset appears more valuable. However, raw volume alone is not an indicator of accuracy.

Atlanta proper has a population of under 500,000. If millions of IPs are assigned directly to the city center without visibility into surrounding municipalities, marketers lose confidence in where those IP addresses actually exist.

This is how IP datasets can become inflated or misleading, especially when city-level precision is claimed without validation.

In this scenario, more is less accurate.

How Digital Element Validates IP Location Using Observed GPS Truth Sets

Because IP addresses do not inherently contain location data, accuracy depends on validating IP-derived location against external signals that reflect where devices are actually observed in the real world.
Digital Element validates IP geolocation accuracy through a rigorous, multi-layered methodology built on decades of expertise. Rather than relying on any single data point, our approach integrates multiple independent validation and behavioral signals to deliver consistently reliable location intelligence. These inputs include high-quality observational datasets, such as mobile device–derived location signals, which are used to continuously verify, refine, and strengthen confidence in IP location assignments.

That GPS-based observation, alongside other validation methods, is used to:

• Verify the general vicinity of the IP address
• Confirm city-level and postal-level placement
• Increase confidence in future lookups tied to that IP range

Digital Element performs this validation at scale.

Each month:

• Over 350+ billion observations
• Across more than 2 billion devices

This allows Digital Element to divide the world into highly granular, real-world geographic segments, including small cities, suburbs, and postal codes.

Digital Element is a trusted IP geolocation provider capable of validating IP location accuracy at this scale.

This view of Atlanta shows IP distribution aligning with where people and infrastructure are concentrated across the metro area, rather than clustering in the city center

Zooming out shows IP distribution matching real population density across the region, not the city center.

Challenges of IP Stability and Why Observation Recency Matters

Another common misconception is that IP addresses are static. In practice, IP addresses are frequently reassigned by ISPs, making location accuracy highly dependent on how recently an IP has been observed and evaluated.

Two providers may assign the same city to an IP address, but without recent observation, that mapping represents only relative confidence.

Digital Element refreshes IP geolocation data on an ongoing basis by:

• Observing IP usage across over a billion mobile devices every 30 days
• Recording the last-seen date of an IP address
• Weighting more recent observations more heavily

For marketers and cybersecurity teams, when an IP was last observed is nearly as important as where it was observed.

Filtering Noise: VPNs, Proxies, and Non-Representative IPsy

Even with robust validation processes in place, IP geolocation still faces inherent challenges. These include VPN traffic, proxy services—such as residential proxies—mobile carrier infrastructure that routes traffic through shared cell towers, and Carrier-Grade Network Address Translation (CGNAT), all of which can obscure a user’s true location and complicate accurate IP assignment.

Digital Element addresses this by layering proprietary methodologies on top of validated data, filtering out IPs that are unlikely to represent meaningful end-user location.

Because Digital Element leverages the largest and most diverse datasets in the industry, it can contextualize IP behavior and remove noise that would otherwise degrade accuracy.

All of this is done within a privacy-centric framework, enabling use cases across AdTech, CTV, cybersecurity, fraud prevention, and content rights enforcement.

Frequently Asked Questions About IP Geolocation Accuracy

How should marketers evaluate city-level IP data accuracy for programmatic success?

Marketers should look beyond raw IP counts and evaluate whether IPs are:

• Validated with recent observations
• Distributed across real population centers
• Refreshed regularly to account for IP reassignment and movement

Accuracy at scale is more important than volume, especially for CTV and programmatic campaigns.

How does IP geolocation compare to device GPS for ad delivery accuracy and scale?

GPS provides high precision but limited scale and availability, particularly on the web.
IP geolocation offers massive reach across connected devices. Digital Element combines IP scale with GPS-based validation, bridging the gap between precision and reach.

How can businesses reconcile app GPS data with web IP location?

The most effective approach is to use GPS data as a validation layer for IP-based location, ensuring consistency across app and web environments. Digital Element’s methodology is designed specifically for this reconciliation.

From Misunderstood Data to Mission-Critical Intelligence

IP geolocation is often misunderstood, but when validated correctly, it becomes a powerful tool for marketing performance, security enforcement, and global digital operations.

To learn how IP geolocation data supports multiple industries, contact Digital Element or explore our Use Cases page.

This is the fifth, and final, installment in our “Targeting and Trust” series of blog posts, dedicated to why IP-based geolocation data is well positioned to deliver both the accurate targeting digital marketers need for improved response rates and the trust consumers crave in terms of personalized promotions in a non-intrusive manner. Here we outline the many different ways IP geolocation can be applied to your marketing efforts.

As we’ve mentioned before, targeting customers by location isn’t new. But as the years have gone by, and location-intelligence technology has improved, brands are finding many new and unexpected applications for geolocation data. Here are some examples.

Find “Clusters of Similarity”

You have a group of users in mind to engage. For example, you might want to target smokers for a public-health campaign. To do this, you can find out the regions with the highest population of smokers, then geofence by IP address to direct your campaigns toward them.

Combine IP Geolocation with “Real-World” Events

When an event is local in nature, brands can factor it in to make a campaign more successful. For example, a clothing retailer could use local weather data to change its front page offers in different regions—bikinis in a heatwave; coats during a cold snap.

Run Time-Sensitive Campaigns

When a brand is running an event that travels across multiple regions, it can phase in or stagger a campaign. For example, a music label could geotarget around a band’s touring schedule.

Look at Buying Patterns by Location to Make Budgets Go Further

This is geolocation “after the fact.” Often, after a campaign has run, the metrics will reveal strong local differences in uptake. Brands can scrutinize this data to make the next round of promotions more effective. These insights can be unexpected. For instance, a company might find it sells more sunscreen in places that get less sun because residents are more likely to travel to hot countries.

Link the Real and Digital Worlds

Often, brands run campaigns to make people take actions in physical locations. IP geolocation presents the chance to connect the dots. So, a retailer might send discount codes to customers and then use IP addresses to see how many recipients responded by visiting local stores.

Target Mobile Users on Wi-Fi

It’s estimated that 80 percent of mobile users connect via Wi-Fi networks, which are generally faster and often cheaper. But these users are invisible to most mobile ad networks. Adding IP geolocation to the stack brings them back. Ad providers can offer targeting by location, without relying on software downloads or user opt-ins.

Add the Ability to Tailor Campaigns to Your Needs

Sometimes you want scale. Sometimes you want to micro-target. It depends on your campaign.

As we’ve discussed, different geolocation approaches deliver different levels of accuracy. GPS and other “lat-long” techniques can pinpoint consumers to a few feet. However, they are limited by the need to have users opt in. This is accuracy at the expense of reach.

Meanwhile, IP geolocation is almost universally available. And, it provides the ability for hyperlocal targeting down to postcode level, globally.

However, some brands have the luxury of choosing from both options. Here’s how it often works. They use IP geolocation to make broadly targeted offers. This builds trust and customer satisfaction. Having established this trust, they ask users to opt in for micro-targeting via GPS. With both IP and GPS available, companies can then run campaigns that favor reach over accuracy or vice versa. They can move the customer down the “purchasing funnel” as required.

Augment Geolocation with Other IP Data Points

In this series, you have read how IP geolocation gives marketers the ability to target effectively by geography—without intruding on privacy. This type of targeting frequently delivers much higher click-through rates. Inventory rates go up, too.

Meanwhile IP geolocation specialists, such as Digital Element, can layer on more targeting attributes besides location. The addition of more IP-based targeting parameters can make campaigns even more effective. Digital Element can give insight into characteristics such as connection speed, Internet Service Provider (ISP), carrier data, home/business types and more. It has also developed an advanced proxy/VPN database.

IP intelligence and geolocation data—and its applications—have evolved over the last several decades to address the ever-changing needs of a global digital marketplace. There’s no better time than the present for brands to explore (or revisit) the use of location-based data in their marketing efforts.

The fourth installment of our five-part blog series digs into the realities of using IP geolocation. Though IP geolocation technology has been around for nearly two decades and is widely used across the globe in a variety of applications, there is still a certain aura of mystery around exactly what this technology is and what it can do. Further, many companies have had negative experiences with IP data providers whose data did not live up to expectations and have, therefore, become disillusioned with the technology’s business potential.

Below we examine the common misconceptions surrounding the use of IP geolocation data and discuss the facts to help you understand the technology’s value and its role in an increasingly location-based digital world.

Misconception: IP-based geolocation data isn’t accurate enough in my country

Many IP providers rely to a large extent on publicly available (free) registration data (i.e. Whois), which is notoriously inaccurate at a city level (less than 50 percent) or even at a country level―and has gaps in coverage upward of 20-to-30 percent where no results are returned.

Reality

Digital Element utilizes patented web-spidering technology and 20⁺ proprietary methods to triangulate the location, connection speed, and many other characteristics associated with an IP address. By combining this “inside-out” infrastructure analysis with “outside-in” user location feedback gleaned from a network of commercial partners, Digital Element can identify where the user actually accesses the internet down to the ISP’s end-point equipment.

Misconception: You must rely on ISPs to get IP geolocation data.

ISPs are notoriously inaccurate in keeping the location information of IP addresses updated in their registries. In fact, most either don’t report location information in the Whois registries or only report the address of their corporate headquarters.

Reality

Digital Element’s proprietary technology traces how traffic is actually routed over the Internet; how routers are connected; and the speed between routers. Then, the data-science team uses this information to triangulate where end-point equipment is located. The company’s technology does not rely solely on data-sharing relationships with ISPs.

Misconception: Because IP addresses are dynamic, it’s impossible to provide accurate geolocation information.

Since most IP addresses are dynamically allocated to some extent, this creates a problem for IP data providers that are solely reliant upon ISP/Whois registration information, as noted above.

Reality

Digital Element bases its mapping on where known pools of dynamic IPs are located. ISP dynamic re-allocations tend to be within those known pools of IP addresses, and the geographic allocation of pools actually remains fairly constant at the ISP end-point equipment level. With more than 10 trillion IP lookups per month, the company is able to pick up IP address reallocations the instant they occur.

Misconception: IP-based information is not as comprehensive as other forms of geolocation data.

Alternative, non-IP based geolocation technologies exist that may provide more granular location information―on small slices of the Internet. They often involve data-gathering techniques that rely on user-provided registration data, cookies, GPS-obtained latitude/longitude coordinates, or HTML5, etc. However, these techniques are far from comprehensive.

Reality

Digital Element’s IP Intelligence and geolocation solutions can provide a comprehensive, non-personally identifiable view of a user’s location within a 3- to 5-mile radius for virtually the entire Internet.

Misconception: Premium IP Intelligence and geolocation solutions are too expensive.

Most IP geolocation vendors simply repackage publicly available (free) Whois registration data and some supplement with user-supplied data, allowing them to offer discounted IP solutions. However, these are not reliable methods for accurate geolocation when used in isolation.

Reality

If coverage, accuracy, and granularity are important, then IP Intelligence and geolocation technology that integrates multiple methodologies, such as Digital Element’s, is the right solution for your business.

As a digital marketer, it’s important to fully understand some of the major differences between IP geolocation solutions and realize that not all IP data providers are created equal.

In Part Five, the final piece of this series, we reveal the many different ways IP geolocation can be applied to your marketing efforts.

Today, we begin our series of blog posts dedicated to why IP-based geolocation data is well positioned to deliver both the accurate targeting digital marketers need for improved response rates and the trust consumers crave in terms of personalized promotions without intrusion. Throughout the series we’ll discuss how IP geotargeting:

• Supports targeting that respects privacy;
• Does not require an opt-in and is, thus, regulation friendly;
• Is immune from the cookie showdown;
• Links physical and digital activity;
• Generates high response rates;
• Commands higher inventory prices;
• Combats click fraud; and
• Unlocks unexpected customer insights.

This first installment of our five-part blog series focuses on how digital marketing has evolved and how location-based targeting fits in to navigating the road ahead.

Even before the pandemic, online activity was booming. However, as COVID-19 forced lockdown after lockdown across the world, more consumers turned to the internet for, well, just about everything—from shopping to entertainment to work and education.

Understandably, ad budgets have taken a collective hit in the last year. However, while traditional media suffered, digital ad spend grew in 2020, up by 6 percent year over year. Even with any lasting effects from the pandemic, the latest estimates predict the global online advertising market to reach $517 billion by 2023.

Yet, for all the good news, digital marketing has come to a crossroads.

Adtech is facing challenges on multiple fronts: privacy issues; falling response rates;  click fraud; regulation; the power of the tech duopoly; and more.

The industry needs to find ways to send targeted messages that give customers real value, while respecting their privacy.

Location-based advertising offers some compelling solutions to the impasse. Geolocation offers a powerful model for targeting. It lets a brand know where its customer is now, and allows for the delivery of more contextually relevant advertising and content.

Many mistakenly believe location-based advertising is only possible when a (mobile) user turns on GPS and gives consent to a brand to access it. But there are other options. This is a relief given how few people choose to opt in to GPS.

The main alternative is IP geolocation. It uses the IP address as the basis for determining location. With the help of additional techniques, IP geolocation is good for targeting users at scale, down to a postcode level—worldwide.

IP geolocation is also entirely anonymous. The IP address reveals nothing personal about the user. This preserves trust and makes the method regulation proof.

Even better, an IP address can say more about an internet connection than its location. It can also identify characteristics such as connection speed and type (mobile or Wi-Fi), the identity of the Internet Service Provider (ISP) and mobile carrier, as well as business insights such as a company name. Brands can use these additional attributes to build even better targeting profiles.

IP geolocation is more than two decades old. It’s well-established. And, it provides the flexibility for marketers to scale—or micro-target—to meet their specific campaign goals.

With conventional targeting techniques coming under pressure, it feels like the start of a new era for IP geolocation technology.

In Part Two of this series, we’ll take a look at the advertising options for digital marketers who want to “go local.”
