When you register a domain, you are requested to give an authentic postal address, email and telephone number in accordance with the policies adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the registrar, but is visible to the public on WHOIS lookup sites too, so anyone can see your info and some people may not be OK with that fact. As a result, numerous registrar companies have come up with the so-called Whois Privacy Protection service, which conceals the domain registrant’s contact info and upon a WHOIS check, people will view the details of the domain registrar, not the domain owner’s. This service is also called Privacy Protection or Whois Privacy Protection, but all these expressions refer to the same service. Nowadays, 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.
