.courses Domain WHOIS & RDAP Lookup

.courses is a generic top-level domain (gTLD). Look up any .courses domain on W.is to see its registrar, registration and expiration dates, status codes and name servers over RDAP, with WHOIS as a fallback.

Example lookup: nic.courses (reserved for the registry operator)

How to look up a .courses domain

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

RDAP lookup

The .courses RDAP endpoint is https://rdap.nic.courses/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.nic.courses/domain/example.courses

WHOIS lookup

The .courses WHOIS server listed by IANA is whois.nic.courses. WHOIS (RFC 3912) is the older plain-text protocol on TCP port 43:

whois -h whois.nic.courses example.courses

Which protocol does W.is use?

W.is queries RDAP first for .courses domains and falls back to WHOIS when the RDAP server returns an error or leaves out data.

Frequently asked questions

What is the WHOIS server for .courses?

The WHOIS server for .courses is whois.nic.courses, as listed in the IANA root zone database. It answers queries on TCP port 43 (for example, whois -h whois.nic.courses example.courses). The .courses registry also offers RDAP, which W.is queries first.

Does .courses support RDAP?

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

How do I check who owns a .courses 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 .courses 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 .courses domain expire?

Each .courses 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. As with other ICANN-contracted TLDs, a .courses registration term can be at most 10 years. Our domain expiration guide explains what happens after a domain expires.
