Registry intelligence
Retrieve the registry allocation record associated with an IPv6 address, including network ownership and registration data.
Cached registry record
This record is a cached response from an internet number registry. It can identify the address allocation or network, but it does not identify an individual device or user.

What WHOIS can tell you
Important limits
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.
