WHOIS is a query and response protocol that provides information about existing domain names and all the pertinent data about them. This includes the owner’s contact details, domain registration, and expiration dates, information about registrars, etc. WHOIS helps you make sure that all the relevant information about a particular registered domain are authentic and up-to-date. This is crucial to prevent fraud and identity theft.

You can think of WHOIS as a private investigator that gives you information about a person of interest. In this case, it will be a domain of interest.
