Common reasons IP location is inaccurate
IP geolocation is often wrong because it estimates location from network data and ISP records rather than GPS, so the city or even country it returns can be inaccurate — especially for VPNs, mobile networks, and corporate IP ranges.
Download CSV| Cause | Why it happens | Example | Typical error | Notes |
|---|---|---|---|---|
| Carrier-Grade NAT (CGNAT) | Mobile users share the same IPs | Mobile ISP IP mapped to HQ | 50-500 km | Super common on 4G/5G |
| Cloud Hosting | The IP actually belongs to a data center | AWS IP shown as US | Country-level | Not the actual user location |
| VPN Services | Your traffic comes out somewhere else | User in EU exits via US | Country-level | That's kind of the point |
| Proxy Networks | People share the same exit nodes | Residential proxy pool | 100-1000 km | Lots of turnover |
| Outdated GeoIP DB | The database hasn't been updated | Reallocated IP | City/region | Updates take time to roll out |
| Anycast Routing | One IP exists in multiple locations | CDN edge IP | City-level | It's how it's supposed to work |
| ISP Centralization | Traffic gets routed through a central hub | Rural user → capital | 50-200 km | Happens a lot in smaller countries |
| Corporate Networks | Traffic leaves through the office | Remote worker | City/region | VPN backhaul |
| Satellite Internet | They map it to the ground station | Starlink user | Country/region | Getting more common |
| IPv6 Transition | IPv4 gets tunneled through IPv6 | 6to4 relay | Country | Old setups still around |
What IP location is actually useful for
- Showing different content based on country
- Spotting fraud and abuse patterns
- Getting a rough idea of where users are
What you shouldn't use IP location for
- Pinpointing someone's exact location
- Figuring out where someone legally lives
