When you register a domain, you are required to give an authentic address, email account and phone number as per the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the registrar, but is available to the general public on WHOIS check websites as well, so anybody can see your information and some people may not be satisfied with this. As a result, lots of domain registrars have come up with the so-called Whois Privacy Protection service, which conceals the domain name registrant’s details and upon a WHOIS lookup, people will see the details of the registrar company, not the domain owner’s. This service is also called Privacy Protection or Whois Privacy Protection, but all these names refer to one and the same service. Now, most of the Top-Level Domains around the world allow Whois Privacy Protection to be added, but there are still country-code extensions that do not support the service.
