Whois Lookup

Find domain registration and ownership information

Frequently Asked Questions

What is WHOIS?
WHOIS is a protocol that queries databases to find the registered owner of a domain name or IP address, including contact information, registration dates, and name servers.
Why is WHOIS information hidden?
Many domain registrars offer WHOIS privacy protection (also called domain privacy) that replaces the owner's personal information with proxy contact details.
How to find domain expiration date?
Use this WHOIS lookup tool to query the domain. The result will show the registration date, expiration date, and last update date.
What is WHOIS privacy protection and should I use it?
WHOIS privacy replaces your personal contact details with a proxy service's information. It protects against spam, identity theft, and domain hijacking. Most domain registrars offer it free or for a small fee.
Can I look up who owns an IP address using WHOIS?
Yes. IP WHOIS queries show the organization that owns the IP block, their contact details, and the Regional Internet Registry (RIR) that allocated it. Use the IP directly in a WHOIS lookup.

What is Whois?

Whois is a query and response protocol used to retrieve information about registered domain names and IP addresses. It provides details such as:

Domain Information: Registrar, registration date, expiration date, and status.

Owner Details: Registrant name, organization, and contact information (when not privacy-protected).

Name Servers: The DNS servers authoritative for the domain.

Technical Contacts: Administrative and technical contact details.

Privacy Protection

Many domain registrars offer Whois privacy protection services that mask the registrant's personal information. This helps protect against spam, identity theft, and unwanted solicitation.

If you see generic registrar contact information instead of personal details, the domain likely has privacy protection enabled.
