How to look up a .淡马锡 domain

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

RDAP lookup

The .淡马锡 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.xn--b4w605ferd

WHOIS lookup

The .淡马锡 WHOIS server listed by IANA is whois.nic.xn--b4w605ferd. WHOIS (RFC 3912) is the older plain-text protocol on TCP port 43:

whois -h whois.nic.xn--b4w605ferd example.xn--b4w605ferd

The commands use the punycode (A-label) form of the TLD, so example.淡马锡 becomes example.xn--b4w605ferd. W.is converts Unicode input for you.

Which protocol does W.is use?

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

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 .淡马锡 registry.
