How accurate is IP geolocation, really?

Short answer: IP geolocation nails the country better than 95% of the time, gets the city right somewhere between 55 and 80% of the time, and cannot find your street or house. Ever. Anyone claiming street-level accuracy from an IP alone is selling something.

Where the data comes from

There’s no official map of IPs to places. Companies like MaxMind and IP2Location build databases by combining provider registration records, network latency measurements, Wi-Fi data, and user-submitted corrections. It’s detective work, not a lookup table. That’s why two geolocation services routinely disagree about the same address.

Registration records tell you who owns a block of addresses and where the company is based — not where the customer using one of them sits today. A provider headquartered in Dallas can serve customers in three states with the same block. Everyone in that block ‘lives’ in Dallas as far as a lazy database is concerned.

Why your location is sometimes way off

Mobile data is the worst case: carriers route traffic through regional gateways, so your phone can geolocate to a city hundreds of miles away. VPNs place you wherever the server is, obviously. Corporate networks route branch offices through headquarters. And satellite internet can put you in another state entirely.

Even on ordinary home broadband, databases lag reality. Providers reshuffle address blocks, and it takes weeks or months for the databases to notice. That’s why your weather widget confidently reports the wrong town — it’s reading an out-of-date guess.

What this means in practice

For businesses, IP location is good enough for currency, language, and rough fraud checks — and terrible for anything requiring precision. For your privacy, it cuts both ways. A stranger with your IP learns your metro area and provider, which is not nothing but is far from your door. The people who can do better — your provider with subscriber records, or apps with GPS permission — aren’t using IP geolocation at all.

Our homepage tool shows the country and network edge your IP currently maps to. If it looks wrong, now you know why — and if it looks right, that’s roughly the best anyone on the internet can do without your help.
