Free WHOIS Domain Lookup — Registrar, Expiry, Nameservers and Registration Date

Our free WHOIS lookup uses the modern RDAP protocol to retrieve domain registration information including registrar, creation date, expiry date and nameservers. Essential for verifying domain ownership, checking expiry before a transfer, investigating suspicious domains and planning domain acquisitions.

RDAP vs Traditional WHOIS

RDAP (Registration Data Access Protocol) is the modern replacement for the old text-based WHOIS protocol. It returns structured JSON data, supports internationalised domain names, and handles privacy-protected registrations more consistently. This tool uses RDAP for all lookups.
