What does WHOIS stand for?

WHOIS stands for "Who Is." It is a protocol used to query databases containing information about registered domain names and their respective owners. The WHOIS protocol allows users to retrieve information about domain registrations, including details such as the domain owner's name, organization (if applicable), email address, physical address, phone number, registration date, expiration date, and registrar information. WHOIS data is publicly accessible and can be queried using WHOIS lookup tools or services provided by domain registrars, registries, and third-party providers.
