When you register a domain, you are requested to give an authentic home address, email and telephone in accordance with the policies approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, however, is not kept only by the registrar, but is visible to the general public on WHOIS check sites too, so anybody can view your info and some people may not be comfortable with that fact. As a result, numerous registrars have introduced the so-called ID Protection service, which hides the registrant’s contact info and upon a WHOIS lookup, people will view the details of the registrar, not the domain owner’s. This service is also known as WHOIS Protection or Privacy Protection, but all these expressions refer to one and the same service. Nowadays, most of the Top-Level Domains around the world allow ID Protection to be added, but there are still country-code extensions that do not support this option.
