IP WHOIS Lookup

See your own public IP address, or enter any IPv4 / IPv6 address or domain name: who the address block is registered to - network range, organisation, ASN and abuse contact, straight from the regional internet registry.

Examples: 8.8.8.8 · 2001:4860:4860::8888 · example.com

Only the official registry RDAP services (and, for a domain, DNS) are asked; the IP address itself is never contacted. Private, local and reserved addresses are not looked up.
