When you register a domain, you have to give a valid home address, email and telephone as per the policy approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the domain name registrar, but is available to the public on WHOIS check websites as well, so anyone can see your information and certain people may not be pleased with that fact. Consequently, a lot of domain name registrars have launched the so-called ID Protection service, which conceals the client’s information and upon a WHOIS lookup, people will view the details of the registrar company, not those of the domain owner. This service is also popular as WHOIS Protection or Privacy Protection, but all these expressions refer to the very same service. At the moment, most of the TLDs around the world allow ID Protection to be added, but there are still country-specific extensions that don’t support this option.
