Whois

Whois is a query and response protocol that provides information about domain ownership, including the registrant’s contact details, domain’s creation and expiration dates, and its associated nameservers.

More about WHOIS

Whenever a domain is registered, the details of that registration are stored in a Whois database.

Anyone can perform a Whois search to find out who owns a particular domain, making it an essential tool for trademark checks, domain purchases, or addressing potential issues.

Due to privacy concerns, many domain owners opt for Whois privacy services to mask their personal information.
