How to look up a .uk domain

The quickest way is to type the domain into the search box above: W.is queries the .uk registry and shows the result in a readable format. You can also query the registry yourself from a terminal.

RDAP lookup

The .uk RDAP endpoint is https://rdap.nominet.uk/uk/domain/. RDAP returns structured JSON over HTTPS (RFC 9082 and RFC 9083); append the domain name to the endpoint:

curl -H 'Accept: application/rdap+json' https://rdap.nominet.uk/uk/domain/example.uk

Which protocol does W.is use?

IANA lists no port-43 WHOIS server for .uk, so W.is looks up .uk domains over RDAP. If the RDAP server returns an error or leaves out data, W.is may still try a legacy WHOIS server.

Frequently asked questions

What is the WHOIS server for .uk?

IANA lists no WHOIS server for .uk. Registration data for .uk domains is available over RDAP instead, at https://rdap.nominet.uk/uk/domain/.

Does .uk support RDAP?

Yes. The .uk RDAP endpoint is https://rdap.nominet.uk/uk/domain/. Append a domain name to it to get the registration data as JSON. W.is uses this endpoint first for every .uk lookup.

How do I check who owns a .uk domain?

Enter the domain in the search box on this page. W.is shows the registrar, registration and expiration dates, status codes and name servers reported by the .uk registry. Owner (registrant) details are often redacted for privacy; in that case the registrar is usually the way to reach the owner. Our guide on how to find a domain owner covers the other options.

When does a .uk domain expire?

Each .uk domain has its own expiration date, set by how long it was registered or renewed for. Look the domain up on W.is to see the expiration date reported by the registry. Our domain expiration guide explains what happens after a domain expires.
