Understanding IP geolocation discrepancies

IP geolocation mismatches

Imagine this: you're trying to log in to your bank's website when a security alert flashes on the screen, flagging your connection as coming from an unexpected city. Or a video streaming service suddenly blocks a show you're trying to watch, claiming it's not available in your region. In both cases, your IP address has sent you on a digital detour, all without you ever leaving home.

This common, yet puzzling scenario is what happens when IP geolocation data goes wrong. It's a quiet story that unfolds every day on the internet, and it's one that network operators and data providers are working together to solve.

The great network dance

The accuracy of IP geolocation is not a single, fixed number. It varies significantly depending on the level of granularity you need. Think of it as a set of concentric circles: the closer you get to a specific point, the less certain the location becomes.

At its heart, an IP address isn't a permanent resident of a single place. The internet is constantly changing as internet service providers (ISPs) and other network operators allocate and manage their networks. ISPs can reassign IP addresses across large geographic areas, acquire new blocks of addresses, or sublease to other operators, leading to a constantly shifting dance of networks.

But these changes don't get broadcast automatically to every corner of the web. First of all, ISPs and network operators are not obligated to report the locations of their networks to the public, though many do so. Sometimes, ISPs don't have perfect visibility into the allocation of all their networks, and do not update public sources about where their networks are being used. Other times, ISPs may update locations to servers that manage an internet connection that may be hundreds of kilometers from the network user's location. These kinds of issues create data discrepancies, where an IP geolocation database still sees the IP address in its old home, while in reality, it's now serving a new location.

These mismatches can cause real-world issues

  • Event or transaction friction: Security systems may flag connections as suspicious, locking users out of accounts or preventing certain actions.
  • Content blocking: Streaming services or websites might restrict access because they think the user is in the wrong region.
  • Incorrectly targeted ads: Location-based advertising may reach users outside the intended region, reducing effectiveness.
  • Skewed analytics: Businesses relying on geolocation for insights may make decisions based on inaccurate data.

For users, these glitches can cause frustration, confusion, and interruptions. For businesses, they can lead to lost revenue, disrupted services, and diminished trust.

Correcting IP location mismatches

For everyday users and companies, this often begins with a simple, two-way street for data correction. Many providers offer tools or portals where a user can submit a data correction for a single IP address that they've found to be wrong. While many providers also allow companies to upload their location data via geofeeds, the core difference for a network operator is moving from this reactive approach to a proactive one. MaxMind makes this shift possible through its GeoIP Exchange program, a more comprehensive collaboration built on two-way communication. Not only do ISPs share their own location data, but MaxMind also provides automated discrepancy discovery to help detect issues and resolve them before they impact end-users.

This alignment is the key to preventing friction, safeguarding user experience, and ensuring the digital world knows exactly where its traffic is coming from.

A shared responsibility

The story of IP geolocation isn't just about a single tool. It's a shared responsibility. While IP geolocation data providers strive to build the most accurate databases, network operators control where and how networks are being used. By working together as partners, they can close the gap between digital data and physical reality, making the internet a more reliable and user-friendly place for everyone.
