When you register a domain, you are obliged to provide an authentic postal address, email and telephone as per the policies adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, however, is not kept only by the domain registrar, but is available to the general public on WHOIS lookup sites as well, so anyone can view your information and lots of people may not be OK with this. As a result, many domain name registrars have launched the so-called ID Protection service, which hides the domain name registrant’s contact info and upon a WHOIS lookup, people will see the details of the registrar company, not the domain owner’s. This service is also known as Privacy Protection or WHOIS Protection, but all these names refer to the exact same service. Nowadays, most of the TLDs around the globe allow ID Protection to be activated, but there are still country-code extensions that do not support the service.
