WHOIS is a protocol that provides public information about registered domains and IP addresses: registrar, registration and expiry dates, name servers and owner/organisation data.

What is the difference between WHOIS and RDAP?

RDAP (Registration Data Access Protocol) is the modern successor to classic WHOIS. It returns structured JSON data and is supported by all major registrars. This lookup is based on RDAP.

Why is WHOIS data often anonymised?

Since the GDPR (2018), personal data of private domain owners from Europe is no longer shown publicly or is replaced by privacy proxies. Registrar, dates and name servers remain visible.
