When you register a domain, you are requested to supply an authentic postal address, email and phone number as per the policies adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, though, is not kept only by the domain registrar, but is available to the general public on WHOIS lookup web sites too, so anybody can check your information and lots of individuals may not be OK with that fact. As a result, many domain name registrars have introduced the so-called ID Protection service, which conceals the domain registrant’s details and upon a WHOIS check, people will see the details of the registrar company, not those of the domain owner. This service is also popular as Privacy Protection or WHOIS Protection, but all these terms refer to the same service. Now, most of the top-level domain names around the world allow ID Protection to be enabled, but there are still country-code extensions that don’t support this service.
