WHOIS Lookup: Domain Registration Information
Our WHOIS lookup tool instantly retrieves domain registration information for any domain. Check availability, registration and expiration dates, registrar details, name servers, and registrant information when publicly available.
WHOIS is a protocol for querying databases that store registration information for domain names. This data is essential for identifying domain owners, investigating potential trademark infringement, and managing domain portfolios.
What Information Does WHOIS Provide?
Domain Availability: Whether the domain is registered or available for purchase.
Registrar: The company where the domain was registered (GoDaddy, Namecheap, etc.).
Registration Dates: When the domain was created, last updated, and when it expires.
Name Servers: The DNS servers that handle the domain's DNS records.
Registrant: The organization or individual who registered the domain (if public).
Domain Status: Status codes like clientTransferProhibited that indicate protections in place.
Understanding Domain Status Codes
clientTransferProhibited: Prevents unauthorized domain transfers. Most domains have this set.
clientDeleteProhibited: Prevents accidental or unauthorized deletion.
pendingDelete: Domain is in the deletion queue after expiration.
redemptionPeriod: Owner has limited time to recover an expired domain.
serverHold: Domain is suspended, usually for non-payment or policy violation.
WHOIS Privacy
Many registrars offer WHOIS privacy services that replace registrant details with proxy information. GDPR in Europe has also led to increased redaction of personal data in WHOIS records. If you see "REDACTED FOR PRIVACY" or similar, the registrant has privacy protection enabled.
FAQ
Why can't I see the owner's name?
The domain owner likely has WHOIS privacy protection enabled, or the registrar is located in a region with privacy regulations like GDPR that require data redaction.
How accurate is the expiration date?
WHOIS expiration dates are generally accurate, but domains often auto-renew before expiration. A domain showing as "expiring soon" may have already been renewed behind the scenes.
