IP WHOIS

Look up the registered owner of any IPv4 or IPv6 address. Queries RDAP at the Regional Internet Registry that allocated the block — ARIN, RIPE, APNIC, AFRINIC or LACNIC — via the global IANA bootstrap.

About

IPv4 and IPv6 address blocks are allocated by IANA to the five Regional Internet Registries — ARIN (North America), RIPE NCC (Europe / ME / Central Asia), APNIC (Asia-Pacific), AFRINIC (Africa) and LACNIC (Latin America / Caribbean). Each RIR runs its own RDAP server. This tool follows the IANA bootstrap so you don't need to know which RIR holds the block.

Backed by rdap.org's federated bootstrap.
