What is a WHOIS lookup?

A WHOIS lookup shows public registration details for a domain (registrar, registration and expiration dates, status codes, and nameservers). Modern registries provide this via RDAP.

Why does WHOIS sometimes hide the owner?

Many registries and registrars redact personal details for privacy and legal reasons. You can still often see registrar info, dates, status, and nameservers.

Privacy note: Many registries redact owner details. This tool focuses on registrar, dates, status, and nameservers. If a registry blocks browser requests (CORS), we automatically try a safe fallback.

What WHOIS tells you

WHOIS data helps with domain transfers, DNS troubleshooting, and basic security checks. This page uses RDAP (structured WHOIS) and selects the correct RDAP server using the IANA RDAP bootstrap.

Common use cases

Check expiration dates to prevent downtime.
Confirm nameservers after DNS updates.
See status codes like clientTransferProhibited (domain lock).
Verify registrar before initiating a transfer.

Status codes (examples)

clientTransferProhibited — transfer lock enabled
clientUpdateProhibited — updates restricted
pendingDelete — domain pending deletion

Note: Some registry RDAP servers may block browser requests (CORS). When that happens, this tool automatically retries via a fallback fetch method to keep it working on static hosting.
