.win Domain WHOIS & RDAP Lookup
.win is a generic top-level domain (gTLD). Look up any .win 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.win (reserved for the registry operator)

How to look up a .win domain
The quickest way is to type the domain into the search box above: W.is queries the .win registry and shows the result in a readable format. You can also query the registry yourself from a terminal.
RDAP lookup
The .win RDAP endpoint is https://rdap.nic.win/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.win/domain/example.winWHOIS lookup
The .win WHOIS server listed by IANA is whois.nic.win. WHOIS (RFC 3912) is the older plain-text protocol on TCP port 43:
whois -h whois.nic.win example.winWhich protocol does W.is use?
W.is queries RDAP first for .win 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 .win?
The WHOIS server for .win is whois.nic.win, as listed in the IANA root zone database. It answers queries on TCP port 43 (for example, whois -h whois.nic.win example.win). The .win registry also offers RDAP, which W.is queries first.
Does .win support RDAP?
Yes. The .win RDAP endpoint is https://rdap.nic.win/domain/. Append a domain name to it to get the registration data as JSON. W.is uses this endpoint first for every .win lookup.
How do I check who owns a .win 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 .win 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 .win domain expire?
Each .win 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 .win registration term can be at most 10 years. Our domain expiration guide explains what happens after a domain expires.
