If you’ve ever wanted to know who registered a particular domain, the domain’s WHOIS information can give you all the answers you need at your fingertips.
Typical WHOIS data can include a name, address, email, phone number, administrative and technical contacts, or other important personally-identifying information. WHOIS is not an acronym. It answers the question, “Who is responsible for this domain?”
Here are nine of the best websites to look up WHOIS information for any domain for free.
Who better to look up WHOIS information with than with ICANN itself? ICANN regulates and provides all WHOIS information.
The regulator’s registration data lookup tool allows you to access the current registration information for any domain name and Internet number resource.

In this case, if you run a WHOIS lookup for such domains, you’ll see the registrar’s WHOIS data instead of the customer’s. However, the registrar has the customer’s details, it just doesn’t make it publicly accessible.
