Whois Domain Tools / Check Domain Whois

Whois is a protocol and service that provides domain ownership and registration information. When a person or organization registers a domain, details such as the registrant's name, physical address, telephone number, and email address are recorded in a Whois database. This information can be public.

Common information includes:

• Domain Name: The unique name identifying a website.
• Registrant: The domain owner's name and contact information.
• Technical Contact: The contact responsible for technical configuration and maintenance.
• Administrative Contact: The contact responsible for administration and management.
• Billing Contact: The contact related to billing and payment.
• Registration Date: When the domain was registered.
• Expiration Date: When registration expires if not renewed.
• Name Servers: Servers responsible for translating the domain into its IP address.

Owners can use Whois to keep registration information accurate and up to date. Others may use it to verify a website's legitimacy, contact an owner about legal or security matters, or conduct research.

Some providers offer Whois privacy services that hide personal information from public results.
