What is a WHOIS Lookup?
WHOIS is a publicly accessible database that stores registration information for every domain name on the internet. When you perform a WHOIS lookup, you query this database to retrieve details about a specific domain.
Originally created in the 1980s, the WHOIS protocol is maintained by ICANN (Internet Corporation for Assigned Names and Numbers) and regional internet registries. It serves as the internet's public directory for domain ownership and is essential for transparency and accountability online.
Note: Many domain owners use WHOIS privacy services to protect their personal contact information from public view. In these cases, proxy information is displayed instead.
What You'll Find in a WHOIS Lookup
Every WHOIS query returns comprehensive domain registration data.
Domain Owner
Registrant name, organization, and contact information (or proxy data if WHOIS privacy is enabled).
Registration Date
When the domain was first registered. Older domains often carry more authority and trust with search engines.
Expiration Date
When the domain registration expires. If it's not renewed, it may become available for others to register.
Name Servers
The DNS servers responsible for resolving the domain. Tells you which hosting or DNS provider the domain uses.
Registrar Info
The company where the domain is registered, along with their IANA ID, abuse contact, and referral URL.
Domain Status
Current EPP status codes like clientTransferProhibited, serverHold, or ok -- indicating the domain's state and restrictions.
Frequently Asked Questions
Common questions about WHOIS lookups and domain information.
Yes, our WHOIS lookup tool is completely free with unlimited searches. No account or registration is required. Simply enter a domain name and get instant results.
Many domain owners enable WHOIS privacy (also called domain privacy or ID protection) to shield their personal contact information from public view. When privacy is enabled, the registrar's proxy service information is displayed instead of the owner's real details.
WHOIS data is sourced directly from ICANN-accredited registrars and is generally up-to-date. However, registrants are responsible for keeping their information current. ICANN requires registrars to verify registrant data periodically, so the information is typically reliable.
Yes. If a WHOIS lookup returns no results or shows "No match for domain," it typically means the domain is available for registration. You can then register it through our domain registration service.
EPP (Extensible Provisioning Protocol) status codes indicate the state of a domain. Common codes include: "ok" (normal, active domain), "clientTransferProhibited" (transfer locked by the registrar), "serverHold" (domain suspended), and "pendingDelete" (domain is being deleted). These codes help understand what actions are permitted on the domain.
