Frequently Asked Questions
What is WHOIS lookup?
WHOIS lookup is a query to retrieve domain registration information including registrar, registration date, expiry date, nameservers, and domain status. It's essentially a public directory of domain ownership information maintained by domain registrars.
What information can I find with WHOIS?
WHOIS provides domain registrar details, registration and expiry dates, nameservers, domain status codes, registrant country/organization (if public), administrative contact information, and DNSSEC status. The exact information available depends on the domain extension and privacy settings.
Why are some WHOIS details hidden?
Many domain owners use privacy protection services (also called WHOIS privacy or domain privacy) to hide personal information from public WHOIS records. This is common for individual registrants to prevent spam, protect privacy, and reduce the risk of identity theft. Business domains often show full registration details.
How often should I check WHOIS?
Check WHOIS before purchasing a domain to verify availability and history, when troubleshooting DNS or email issues, to monitor domain expiry dates for critical domains, when researching website ownership for business purposes, or when investigating suspicious domains for security reasons.
Can I lookup any domain extension?
This tool supports most common domain extensions including .com, .net, .org, .info, and many country-code TLDs (ccTLDs). Some newer or specialized generic TLDs (gTLDs) may have limited WHOIS data available due to different registry policies.
What do domain status codes mean?
Domain status codes indicate the current state of a domain. Common codes include: clientTransferProhibited (transfer locked), clientUpdateProhibited (update locked), clientDeleteProhibited (delete locked), and ok (normal status). These codes help protect domains from unauthorized changes.
Is WHOIS lookup legal?
Yes, WHOIS lookups are completely legal and part of the domain registration system. WHOIS data is public information required by ICANN (Internet Corporation for Assigned Names and Numbers) to be accessible for transparency and accountability purposes.
