IP Geolocation
Look up the geographic location, ISP, and ASN for any IP address or domain. Shows country, region, city, and coordinates.
How to Use IP Geolocation
- 1Enter an IP address (IPv4 or IPv6) or domain name.
- 2Click Look Up to query geolocation data.
- 3View country, region, city, ISP, and ASN details.
- 4Use the coordinates to find the approximate location on a map.

Frequently Asked Questions
How accurate is IP geolocation?▾
IP geolocation accuracy varies by granularity. Country-level accuracy is typically 95-99%. Region/state accuracy is around 55-80%. City-level accuracy is 50-75%. Coordinates are approximate — often representing the center of a city or ISP region, not an exact physical location. Accuracy is lower for mobile networks (where IPs are assigned regionally by carrier) and VPNs/proxies (where the IP belongs to the VPN provider's location).
What is an ASN (Autonomous System Number)?▾
An ASN is a unique identifier assigned to a network of IP addresses under a single administrative control (an internet service provider, company, or university). BGP routing uses ASNs to exchange routing information between networks. ASNs are assigned by IANA and regional registries (ARIN, RIPE, APNIC). For example, AS15169 is Google, AS32934 is Facebook. Knowing the ASN tells you which organization controls the IP block.
Why does the IP location not match the physical location?▾
Several factors cause mismatches: (1) VPNs and proxies — the IP belongs to the VPN server's location, not the user's. (2) Mobile networks — carriers use regional IP pools that may be in a different city. (3) Large ISPs — may register IPs at their HQ location even when serving other areas. (4) CDNs — servers have anycast IPs that may resolve to the nearest PoP. (5) Outdated databases — IP reassignments take time to propagate to geolocation databases.
What is the difference between IPv4 and IPv6?▾
IPv4 uses 32-bit addresses (e.g., 192.168.1.1) giving ~4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) giving 340 undecillion addresses. IPv4 exhaustion has been addressed through NAT and CIDR, but IPv6 adoption is increasing. Most networks run dual-stack. IPv6 geolocation is generally less precise than IPv4 because IPv6 databases are less mature and ISPs assign /48 or /64 prefixes to customers.
Can I look up a domain name instead of an IP?▾
Yes — entering a domain name will first resolve it to an IP address via DNS (A or AAAA record), then geolocate that IP. The result shows the resolved IP along with location data. Note that large sites (Google, Facebook, Cloudflare) use anycast or geographically distributed infrastructure, so the resolved IP may be the nearest edge node to our lookup server, not necessarily the origin server.
