When you register a domain, you are asked to supply an authentic address, email and telephone in accordance with the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the registrar, but is available to the public on WHOIS sites too, so anybody can see your info and many people may not be happy with this. As a result, plenty of domain registrars have come up with the so-called ID Protection service, which hides the registrant’s contact details and upon a WHOIS lookup, people will see the details of the registrar, 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. Currently, most of the Top-Level Domains around the world allow ID Protection to be enabled, but there are still country-code extensions that do not support this service.
