IP Geolocation & Reverse IP Lookup
Find the city, country, ISP and ASN behind any IP address or domain.
Geolocation
Enter an IP address or domain, or look up your own address.
How to read this
- Geolocation is an estimate from registry and routing data — city accuracy is usually good, street level never is.
- The PTR record is the reverse DNS name the address owner published. Hosting providers usually set one; home connections often do not.
- ASN and ISP tell you which network announces the address, which is the most reliable field here.
- Mobile and VPN addresses commonly resolve to the provider's gateway city, not the user's.
About the IP Geolocation & Reverse IP Lookup
Enter any public IPv4/IPv6 address or domain to see its estimated location, timezone, ISP, organisation and ASN, plus a reverse DNS (PTR) lookup. One click looks up your own address.
