How IP geolocation works
The displayed location is where IP geolocation databases place your public IPv4 address. It is an estimate based on how your ISP uses that address, not a GPS reading, and it doesn’t come from your device. It is usually accurate at the country level and often, but not always, at the city level.
Where IP location data comes from
There is no official register that links IP addresses to places. Geolocation providers build their databases by combining several sources:
- Registry records: regional internet registries such as RIPE NCC and ARIN record which organization holds each IP range and its country.
- ISP information: some providers publish geolocation feeds that say where they use each range.
- Network measurements: timing how fast data travels to an address helps narrow down where it is.
- User-submitted data: location-aware apps and correction requests help refine the results.
How accurate is IP geolocation?
Accuracy drops the more precise the result:
- Country: correct in the vast majority of cases.
- Region or state: usually correct for fixed home and business connections.
- City: often correct, but many lookups land on the nearest large city or your ISP’s hub.
- Street address: not possible from an IP address alone.
Mobile connections are the least precise, because carriers route traffic through a small number of central gateways that may be hundreds of kilometers away.
What websites use your IP location for
- showing content in your language and currency
- enforcing streaming and licensing regions
- fraud prevention, such as flagging a login from an unusual country
- local search results, weather and news
- compliance with regional laws, such as privacy and gambling rules
Why your location might look wrong
If the result is far from where you are, check whether you’re connected to a VPN or proxy first. If you aren’t, your ISP may have recently moved that address range, or it routes your traffic through another city. The hostname and ISP linked to your IP can help explain which network you are on.
