When you register a domain name, you need to supply an authentic home address, email and telephone as per the policies approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, though, is not kept only by the registrar company, but is available to the general public on WHOIS lookup sites as well, so anyone can see your details and certain people may not be okay with that fact. As a result, a lot of companies have launched the so-called Whois Privacy Protection service, which hides the domain registrant’s contact information and upon a WHOIS check, people will see the details of the registrar, not those of the domain owner. This service is also known as Whois Privacy Protection or Privacy Protection, but all these expressions refer to the same service. Today, most of the TLDs around the globe allow Whois Privacy Protection to be added, but there are still country-code extensions that don’t support this service.
