.mtr Domain WHOIS & RDAP Lookup

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

How to look up a .mtr domain

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

RDAP lookup

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

WHOIS lookup

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

whois -h whois.nic.mtr example.mtr

Which protocol does W.is use?

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

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

Does .mtr support RDAP?

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

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

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