Domain WHOIS Lookup

Enter a domain name to look up its WHOIS information including registration date, expiry date, and name servers.

  1. Enter the domain name you want to look up in the search box above (e.g. google.com). No need to include http:// or any path.
  2. Click the Look Up button or press Enter.
  3. Results will appear in a table within 1–3 seconds, showing the domain status, registrar, registration date, expiry date, and name servers.
  4. Fields showing «—» indicate that the domain's WHOIS data is not publicly available, or that the TLD does not yet support the RDAP protocol.

This tool uses RDAP (Registration Data Access Protocol), the modern standard promoted by ICANN to replace traditional WHOIS. Data is fetched directly from the domain's registry in structured JSON format.

When would you use this tool?

Before buying a domain to check if it's taken; investigating who owns a website; verifying name server configuration; or monitoring a competitor's domain expiry date to find acquisition opportunities.

What's the difference between WHOIS and RDAP?

Traditional WHOIS uses plain text over TCP port 43, with inconsistent output formats that are difficult to parse programmatically. RDAP is ICANN's modern successor protocol that returns well-structured JSON data with support for fine-grained access control and privacy filtering. This tool uses RDAP.

What do the domain status codes mean?

Common statuses: clientTransferProhibited (cannot be transferred to another registrar), serverDeleteProhibited (registry-level delete lock), pendingDelete (will be deleted soon, may become available), redemptionPeriod (can be recovered for a fee before deletion).

Why can't some domains be found?

Possible reasons: (1) the domain has never been registered; (2) the TLD doesn't support RDAP yet (some ccTLDs still only support legacy WHOIS); (3) the registrant has enabled a privacy protection service that hides contact details.

Is WHOIS information always accurate?

Not necessarily. WHOIS data is self-reported by registrants and may be incomplete or inaccurate. Since GDPR, personal information for EU-based registrants is typically shown via privacy proxy rather than real contact details.
