How to look up a .calvinklein domain

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

RDAP lookup

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

Which protocol does W.is use?

IANA lists no port-43 WHOIS server for .calvinklein, so W.is looks up .calvinklein domains over RDAP. If the RDAP server returns an error or leaves out data, W.is may still try a legacy WHOIS server. Since January 28, 2025, ICANN no longer requires gTLD registries to run a WHOIS service, and RDAP is the authoritative source of gTLD registration data.

Frequently asked questions

What is the WHOIS server for .calvinklein?

IANA lists no WHOIS server for .calvinklein. Registration data for .calvinklein domains is available over RDAP instead, at https://rdap.nic.calvinklein/domain/.

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

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