.java Domain WHOIS & RDAP Lookup

.java is a generic top-level domain (gTLD). Look up any .java 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.java (reserved for the registry operator)

How to look up a .java domain

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

RDAP lookup

The .java RDAP endpoint is https://rdap.identitydigital.services/rdap/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.identitydigital.services/rdap/domain/example.java

WHOIS lookup

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

whois -h whois.nic.java example.java

Which protocol does W.is use?

W.is queries RDAP first for .java 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 .java?

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

Does .java support RDAP?

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

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

Each .java 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 .java registration term can be at most 10 years. Our domain expiration guide explains what happens after a domain expires.
