WHOIS
WHOIS is a publicly accessible lookup system used to find information about who owns a domain name or IP address. It functions like a “domain registration record” that stores details such as the registrant’s name, organization, registrar, registration date, and expiration date (unless privacy protection is enabled).
WHOIS records are managed by domain registries and registrars and are commonly used in domain management, cybersecurity, and legal investigations.

A marketer wants to purchase the domain examplebrand.com, but it is already taken. They use a WHOIS lookup tool to see when the domain was registered, when it expires, and whether the owner has enabled privacy protection. If contact details are visible, they may reach out with a purchase offer.
