When you register a domain, you need to give a genuine street address, email and telephone as per the policies adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the domain registrar, but is visible to the public on WHOIS lookup web sites too, so anybody can see your information and some people may not be okay with that fact. Consequently, numerous registrar companies have come up with the so-called ID Protection service, which hides the domain registrant’s details and upon a WHOIS lookup, people will see the details of the domain registrar, not the domain owner’s. This service is also popular as Privacy Protection or WHOIS Protection, but all these expressions refer to the very same service. At the moment, most of the Top-Level Domains around the globe allow ID Protection to be added, but there are still country-specific extensions that don’t support this service.
