WHOIS Domain Lookup

WHOIS is a protocol used to query databases that store information about registered domain names. A WHOIS lookup provides details about a domain's registration, including the owner's contact information, registration dates, name servers, and more.

WHOIS lookups are useful for checking domain availability, investigating ownership of a domain, finding contact information for domain administrators, checking registration and expiration dates, and identifying potential trademark conflicts.

Many domain registrars offer WHOIS privacy protection services that replace the registrant's personal contact information with generic registrar information. This is done to prevent spam and protect privacy while still complying with ICANN regulations.

WHOIS databases are typically updated in real-time when changes are made to domain registrations. However, some registries may take a few hours to propagate updates across all WHOIS servers.
