IP Lookup

Ready

Read public IP allocation and registration data through RDAP. This is not precise geolocation.

All tools are free to use. File size and processing limits may vary by tool.

How to use

Your connection’s public IP and estimated country appear automatically. Copy the address or request network name, registered organization and address range. You can also query another public IPv4/IPv6 address. Detailed lookups send the IP to RDAP registry services. VPNs/proxies may change the visible IP; country estimates are not precise location.

How are files processed?

Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
