What is WHOIS?

WHOIS is a public database that stores registration information for domain names. A WHOIS lookup reveals who registered a domain, when it was created, when it expires, the registrar, nameservers, and domain status. This information is useful for verifying domain ownership, checking availability, and investigating suspicious domains.
