When you register a domain name, you need to provide an authentic home address, email and phone in accordance with the policy adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, though, is not kept only by the registrar, but is available to the general public on WHOIS websites as well, so anybody can view your details and many people may not be OK with that fact. As a consequence, plenty of domain name registrars have come up with the so-called ID Protection service, which hides the registrant’s contact information and upon a WHOIS lookup, people will see the details of the registrar company, 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. At the moment, most of the TLDs around the globe allow ID Protection to be added, but there are still country-specific extensions that don’t support the service.
