When you register a domain, you are obliged to provide a valid postal address, email and phone number as per the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the domain registrar, but is visible to the general public on WHOIS lookup sites too, so anybody can view your info and many individuals may not be pleased with that fact. As a consequence, numerous companies have launched the so-called ID Protection service, which conceals the client’s info and upon a WHOIS check, people will view the details of the registrar company, not the domain owner’s. This service is also called Privacy Protection or WHOIS Protection, but all these terms refer to the same service. Now, most of the TLDs around the world allow ID Protection to be enabled, but there are still country-specific extensions that don’t support this service.
