The most important questions and answers about our free WHOIS lookup.
A WHOIS lookup shows publicly available information about a domain, such as the registrar, the registration and expiry dates, and the domain's status. It helps you quickly check a domain's availability and origin.
Depending on the domain extension and privacy settings, a WHOIS lookup usually shows the responsible registrar, the creation and expiry date, the nameservers used, and the domain's current status. Personal contact details are now hidden for many extensions for privacy reasons.
WHOIS privacy hides the domain owner's personal contact details from public lookup and instead shows anonymized placeholder data. This protects owners from spam and misuse of their contact information.
