When you register a domain name, you have to supply an authentic home address, email and telephone as per the policy adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the registrar, but is available to the general public on WHOIS lookup sites as well, so anyone can view your info and many individuals may not be comfortable with this. As a result, numerous companies have come up with the so-called ID Protection service, which hides the domain registrant’s contact info 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 Protection or Privacy Protection, but all these terms refer to the same service. As of now, most of the Top-Level Domains around the world allow ID Protection to be added, but there are still country-specific extensions that don’t support this option.
