How to look up a .amsterdam domain

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

RDAP lookup

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

WHOIS lookup

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

whois -h whois.nic.amsterdam example.amsterdam

Which protocol does W.is use?

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

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

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