When you register a domain, you are obliged to supply an authentic address, email account and telephone as per the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the domain registrar, but is visible to the general public on WHOIS sites as well, so anyone can check your details and some people may not be comfortable with that fact. As a result, lots of domain registrars have introduced the so-called ID Protection service, which hides the client’s details and upon a WHOIS lookup, people will view the details of the domain registrar, not those of the domain owner. This service is also popular as WHOIS Protection or Privacy Protection, but all these names refer to the very same service. As of now, most of the Top-Level Domains around the world allow ID Protection to be activated, but there are still country-code extensions that don’t support this option.
