IP Location Lookup

IP geolocation relies on WHOIS databases, BGP routing data, and commercial databases like MaxMind. ISPs register IP ranges with Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC). Geolocation providers cross-reference routing tables, registration data, and user-reported corrections to map IP ranges to geographic regions.

IP geolocation is typically accurate to country level (95%+), region level (80%), and city level (50–80%). Error margins of 25–50 km are common. Mobile networks often geolocate to the carrier headquarters, not your actual location. Corporate VPNs show the corporate office IP.

IP geolocation powers fraud detection, content localization, and regulatory compliance. Security teams use it during incident response to trace attack origins. CDN providers route requests to the nearest edge server. E-commerce platforms display local currency and delivery options automatically.

When using a VPN, the geolocation shows the VPN server location, not yours. Tor exit nodes show the exit node's location. Some platforms block or challenge logins when the geolocation differs significantly from the registered account location.

IPv6 geolocation databases are less mature than IPv4, leading to lower accuracy. Many IPv6 blocks are allocated in large chunks to ISPs without granular location data. As IPv6 adoption grows, providers are improving coverage. Expect higher uncertainty for IPv6 lookups, especially for mobile carriers.
