Frequently Asked Questions

What is WHOIS information?
WHOIS information is a public database that contains details about domain name registrations, including domain owner contact information, registrar details, registration and expiration dates, name servers, and domain status. This information is publicly available for most domain extensions.

Is this WHOIS lookup tool free?

What information can I get from a WHOIS lookup?
WHOIS lookup provides domain ownership details (registrant name, organization, email), registrar information (who registered the domain), registration and expiration dates, name servers, domain status, and sometimes contact information. Note that some registrars offer privacy protection which may hide contact details.

Why is some WHOIS information hidden?
Many domain registrars offer WHOIS privacy protection services that hide the actual registrant's contact information to prevent spam and protect privacy. Instead, you'll see the registrar's proxy contact information. This is a common practice and doesn't indicate anything suspicious.

Can I lookup any domain extension?
Yes, you can lookup most common domain extensions (.com, .net, .org, .io, .co, etc.). However, some country-code domains (.uk, .de, etc.) may have different WHOIS databases or restrictions. The tool works best with generic top-level domains (gTLDs).

How accurate is WHOIS information?
WHOIS information comes directly from domain registrars and is generally accurate. However, contact information may be outdated if domain owners haven't updated their records. Expiration dates and registration dates are typically very accurate.

What can I use WHOIS lookup for?
WHOIS lookup is useful for domain intelligence, competitor research, checking domain availability, verifying domain ownership, investigating suspicious domains, checking expiration dates before purchasing expired domains, and understanding domain registration history.
