Frequently asked questions

What data does WHOIS show?
WHOIS can show registrar details, registration dates, and contact information for a domain, though much of it is now privacy-protected.

RDAP is the modern, JSON-based protocol that replaces legacy WHOIS for registries and RIRs.
Does WHOIS show the real owner?
Not always. Many domains use privacy protection, which hides personal details from public WHOIS records.
