The Free Whois Lookup Tool allows you to investigate the ownership and registration details of any domain name. WHOIS is a widely used query and response protocol for querying databases that store the registered users or assignees of an Internet resource.
Our tool starts by querying the IANA root database and automatically follows "referral" pointers to finding the specific authoritative WHOIS server for that TLD (Top Level Domain). This ensures you get the most accurate and up-to-date raw data available.
