About WHOIS Lookup
What is WHOIS?
WHOIS is a widely-used protocol for querying databases that store information about registered domain names. When you perform a WHOIS lookup, you can find details about who owns a domain, when it was registered, when it expires, and which registrar manages the domain. This information is publicly available for most domain extensions.
What Information Does WHOIS Provide?
A typical WHOIS record includes the domain name, registrar information, registration and expiration dates, name servers, domain status codes, and often contact information for the registrant, administrative contact, and technical contact. However, many domain owners use privacy protection services that mask their personal information.
Common Uses for WHOIS Lookup
- Checking domain availability before registration
- Verifying the legitimacy of a website
- Finding contact information for domain owners
- Investigating trademark or copyright issues
- Troubleshooting DNS and hosting problems
- Checking domain expiration dates
Privacy and WHOIS
Due to privacy regulations like GDPR, many registrars now offer or require WHOIS privacy protection. This replaces the registrant's personal information with the registrar's or a proxy service's details. If you need to contact a domain owner with privacy protection, most registrars offer a forwarding service.
