Domain WHOIS Lookup

Who registered a domain? Check the authoritative RDAP record for its registrar, public contacts, important dates, and nameservers.

Use the registered domain, not a subdomain. International domain names are supported. A website URL without a query string also works.

Your submitted domain is sent to Swarme and the registry identified by IANA. This tool does not save lookup results or reveal privacy-protected ownership details. Do not use public contacts for spam.

Understand a domain’s registration

Query the registry selected by the IANA RDAP bootstrap directory. Review publicly available registrar and contact details, registration and expiration events, domain status, nameservers, and DNSSEC.

WHOIS is the familiar name for registration lookup; this tool uses modern HTTPS RDAP. Missing ownership information may be redacted or omitted. No record does not prove that a domain is available to buy.
