IP Address Lookup
About the IP Address Lookup
The IP Address Lookup tool reveals the geographic location, internet service provider, organization, autonomous system number, and other public information attached to any IP address. Network administrators, security analysts, marketers, journalists, and curious users rely on it daily to investigate suspicious traffic, verify the location of visitors, troubleshoot connectivity issues, or simply learn about an unfamiliar address from server logs.
What information is revealed
For any public IPv4 or IPv6 address, the lookup returns the country, region, city, postal code, latitude and longitude, the internet service provider (ISP) and organization that owns the address block, the autonomous system (AS) number, the time zone, and whether the address belongs to a known data center, VPN, or proxy network. None of this requires special access — it comes from public WHOIS and BGP databases.
How to use it
- Enter any IP address in IPv4 or IPv6 format.
- Or leave the field blank and click Look Up My IP to inspect your own address.
- Read the results and copy any field you need.
Common use cases
Investigating suspicious login attempts in server logs, verifying that a user actually browses from the country they claim, checking whether a connection comes from a known VPN or data center, debugging geo-IP routing in CDN configurations, learning where third-party API requests originate, and preparing incident reports for security investigations.
Privacy and accuracy
Lookups query public WHOIS, RIR, and geolocation databases. We do not store the addresses you look up. Geolocation is approximate — city-level accuracy is typical for residential ISPs, while addresses on mobile carriers or large datacenters may resolve to the carrier’s headquarters rather than the actual device location. For exact location, GPS or device-level APIs are required.
