When you register a domain, you have to supply a valid home address, email and telephone in accordance with the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, though, is not kept only by the domain registrar, but is available to the general public on WHOIS check websites as well, so anybody can view your info and lots of people may not be pleased with this. As a result, a lot of registrar companies have come up with the so-called Whois Privacy Protection service, which hides the registrant’s contact info and upon a WHOIS lookup, people will see the details of the registrar company, not the domain owner’s. This service is also known as Whois Privacy Protection or Privacy Protection, but all these terms refer to one and the same service. As of 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 don’t support this service.
