IPv6 WHOIS
IPv6 WHOIS Lookup - Find IPv6 Owner
Look up registration and ownership information for an IPv6 address.
How It Works
Similar to IPv4 WHOIS, but queries registries for IPv6 allocation information. IPv6 blocks are typically much larger than IPv4.
Understanding Results
Results show the organization allocated the IPv6 block, prefix size, registry, and contact information.
