Registry intelligence

IPv6 WHOIS lookup

Retrieve the registry allocation record associated with an IPv6 address, including network ownership and registration data.

Example: 2001:4860:4860::8888
How IPv6 WHOIS and RDAP work

Submitting this form may retrieve and cache one registry record. Direct result URLs only display records already in cache.

What WHOIS can tell you

Network allocation and registry context

  • •Which registry returned the record and the network range it covers.
  • •Organization, contact, status, and allocation fields when published by the registry.
  • •Technical identifiers and links that help investigate routing or ownership questions.

Important limits

Registry data is not personal location data

A registry record describes an address allocation. It can be incomplete, may represent a provider rather than an end customer, and may change as networks are reassigned. Use it alongside routing and network evidence when investigating an address.
