When you register a domain, you have to supply an authentic postal address, email and phone number in accordance with the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, though, is not kept only by the registrar, but is visible to the general public on WHOIS sites as well, so anyone can check your information and some people may not be happy with this. Consequently, plenty of domain registrars have introduced the so-called Whois Privacy Protection service, which hides the domain registrant’s information and upon a WHOIS check, people will see the details of the registrar company, not the domain owner’s. This service is also called Whois Privacy Protection or Privacy Protection, but all these expressions refer to one and the same service. Today, most of the TLDs around the world allow Whois Privacy Protection to be enabled, but there are still country-code extensions that don’t support this option.
