Frequently asked questions
What information does a WHOIS lookup show?
Registration and expiration dates, the registrar, nameservers, and (when not privacy-protected) the registrant's contact details for a domain.
Why is the owner information sometimes hidden?
Many registrars offer (or require, under regulations like GDPR) WHOIS privacy protection, which replaces the real registrant details with the registrar's proxy contact information instead.
Can I use this to check if a domain is available to register?
Yes - if a WHOIS lookup returns no registration record, that's a strong signal the domain is available, though you should confirm directly with a registrar before assuming so.
