Domain WHOIS Lookup (RDAP)
Registrar, dates, status codes and nameservers for any domain.
This check runs through this site's own server, so it works for any public URL — no CORS or browser restrictions. Lookups use RDAP, the modern replacement for the legacy WHOIS protocol.
How to use the Domain WHOIS Lookup (RDAP)
- 1 Enter a domain name and click Lookup WHOIS.
- 2 Check the registrar and the created, updated and expiry dates.
- 3 Review the domain status codes and nameservers, and whether DNSSEC is enabled.
Frequently asked questions
What is RDAP, and how is it different from WHOIS?
RDAP (Registration Data Access Protocol) is the modern, structured-JSON replacement for the old plain-text WHOIS protocol. It is being adopted across registries and registrars and is what this tool queries, even though people still commonly call this kind of lookup "WHOIS".
Why do some domains return no data, or partial data?
Not every top-level domain registry runs an RDAP server yet, and some registrars redact registrant details for privacy (especially since GDPR). Registrar, dates and nameservers are usually still available even when contact details are hidden.
What do status codes like clientTransferProhibited mean?
These are standard EPP status codes. clientTransferProhibited and clientDeleteProhibited mean the registrar has locked the domain against transfer or deletion (often the default, protective state); clientHold means the domain has been taken out of DNS. The tool shows a short explanation next to each code returned.
Why does "expires in N days" matter?
Domains that aren't renewed in time can lapse, enter a costly redemption period, or even be re-registered by someone else once released — checking the expiry date is a quick way to catch a renewal you might have missed.
