This free tool can reveal who is behind any internet domain

Uncover the owner, age, and contact details of any website using the free WhoIs lookup tool. Simply searching a domain name in Google won't provide this level of detail. The WhoIs tool, maintained by the Internet Corporation for Assigned Names and Numbers (ICANN), offers a comprehensive view of domain registration information.

Website registration requires the registrant to supply contact information to the registrar, which is essential for maintaining the website's operational status. The WhoIs search reveals this information, although some details, particularly contact information, may be kept private.

Below is a breakdown of the information you'll typically find in a WhoIs lookup:

  • Domain Name: The website's domain name.
  • Internationalized Domain Name (IDN): Displays the domain name in non-Latin scripts if applicable (e.g., Arabic, Greek).
  • Registry Domain ID: The unique identifier assigned by the domain's registry.
  • Domain Status: Indicates the domain's current status (e.g., "active," "ok"). Refer to ICANN's documentation for a complete list of status codes.
  • Nameservers: The servers directing users to the website. These handle the translation of domain names to IP addresses.
  • Dates: Key dates such as registration date and expiration date.
  • Contact Information: May include contact details for the registrant and other associated individuals. Note: this information may be redacted for privacy reasons.
  • Registrar Name: The company hosting the domain name (e.g., GoDaddy, Namecheap).
  • IANA ID: The identifier assigned by the Internet Assigned Numbers Authority (IANA) to the registrar.
  • Abuse Contact: Contact information for reporting domain abuse or illegal activity.
  • Reseller Information: Details about any reseller involved in the domain registration.
  • DNSSEC Delegation Signed: Indicates whether DNSSEC security is enabled.
  • DS Data and Key Data: Data related to DNSSEC keys.
  • Authoritative Servers: The servers providing the WhoIs data, along with their last update time.
  • RDAP Responses: Raw data in Registration Data Access Protocol (RDAP) format.

For a complete explanation of any unfamiliar terms, consult ICANN's glossary.
