WHOIS Lookup
Find domain registration details, ownership, and expiry information.
What is WHOIS?
WHOIS is a query and response protocol used to look up information about registered domain names. When someone registers a domain, their contact information is stored in a WHOIS database maintained by the registrar or registry.
Since the implementation of GDPR in 2018, most personal registrant data is redacted for privacy. However, you can still find useful information including the registrar, registration dates, name servers, and domain status codes.
WHOIS lookups are commonly used to check domain availability, verify ownership, investigate potential trademark conflicts, and troubleshoot DNS issues.
Frequently Asked Questions
What is a WHOIS lookup?
A WHOIS lookup queries public databases to find domain registration details including the registrar, creation/expiry dates, name servers, and status.

Historically yes, but since GDPR most personal data is redacted. Technical and registrar information typically remains accessible.
Why is WHOIS data redacted?
Privacy regulations like GDPR require registrars to protect personal data. Most registrars now offer free WHOIS privacy protection.
How do I find who owns a domain?
Use a WHOIS lookup tool. If privacy protection is enabled, you may need to contact the registrar directly through their abuse or privacy relay email.
