IP Address Lookup

Look up which network an IP address belongs to and who it's registered to, from the regional registry.

What this tool shows

Who an IP address is officially allocated to, straight from the regional internet registry (ARIN, RIPE NCC, APNIC, LACNIC, or AFRINIC) over RDAP. The lookup runs on our server, so it is never sent to a third-party service.

It does not show a city. Street- or city-level geolocation for an arbitrary IP requires a licensed commercial database that we do not use, and every free API that claims otherwise is guessing. We would rather show you less and have it be true.
