Data comes live from the official registry via RDAP — the modern, structured successor to WHOIS. Personal registrant details are usually redacted for privacy (GDPR).

What is WHOIS / RDAP?

WHOIS is the public directory of domain registrations. It answers questions like: when was this domain registered, when does it expire, which registrar manages it, and which name servers does it use. This tool uses RDAP — the modern, structured successor to WHOIS mandated by ICANN — and reads live data from the official registries.

Since GDPR (2018), personal registrant names, emails and addresses are redacted in most WHOIS output. The registration dates, registrar, status codes and name servers remain public, and those are usually what you need to evaluate a domain's age, legitimacy or availability.

How to use

  2. 02Click WHOIS lookup — data comes live from the official registry via RDAP.
  3. 03Review the registrar, registration and expiry dates, status and name servers.
  4. 04A 'not found' result usually means the domain is unregistered.

Frequently asked questions

Why don't I see the owner's name and email?
Since GDPR in 2018, registries and registrars redact personal contact details from public WHOIS/RDAP output. Registration dates, registrar, status and name servers remain public.
What is RDAP and why use it instead of classic WHOIS?
RDAP (Registration Data Access Protocol) is ICANN's official successor to WHOIS. It returns structured JSON from the authoritative registry over HTTPS, which makes it more reliable and machine-readable than scraping legacy WHOIS text.
What do status codes like clientTransferProhibited mean?
They are EPP status codes. clientTransferProhibited means the registrar has locked the domain against transfers — a normal anti-hijacking protection. serverHold, by contrast, means the registry has suspended the domain.
Does a 'not found' result mean the domain is available?
Usually yes for common TLDs — but some country-code TLDs do not support RDAP yet. Confirm availability with a registrar before making decisions.
