When you register a domain, you are requested to provide an authentic home address, email account and phone in accordance with the policy adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, though, is not kept only by the domain registrar, but is visible to the public on WHOIS check websites too, so anyone can see your information and a lot of people may not be okay with that fact. As a consequence, lots of domain registrars have introduced the so-called Whois Privacy Protection service, which hides the domain name registrant’s information and upon a WHOIS lookup, people will see the details of the registrar, not the domain owner’s. This service is also called Privacy Protection or Whois Privacy Protection, but all these terms refer to the same service. Now, most of the top-level domain names around the world allow Whois Privacy Protection to be activated, but there are still country-code extensions that don’t support this option.
