When you register a domain, you need to supply a valid address, email and phone number in accordance with the policy adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the registrar company, but is accessible to the public on WHOIS lookup web sites as well, so anybody can check your information and a lot of individuals may not be pleased with that fact. As a result, a lot of domain registrars have launched the so-called ID Protection service, which hides the domain name registrant’s info and upon a WHOIS check, people will view the details of the registrar, not those of the domain owner. This service is also called Privacy Protection or WHOIS Protection, but all these expressions refer to the very same service. As of now, most of the top-level domain names around the world allow ID Protection to be enabled, but there are still country-specific extensions that don’t support this service.
