When you register a domain name, you have to give a valid postal address, email and phone number as per the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the registrar company, but is accessible to the public on WHOIS lookup websites as well, so anybody can see your details and lots of individuals may not be happy with this. As a result, lots of registrar companies have introduced the so-called ID Protection service, which conceals the domain name registrant’s info and upon a WHOIS check, people will view the details of the domain registrar, not the domain owner’s. This service is also popular as Privacy Protection or WHOIS Protection, but all these terms refer to the very same service. As of now, most of the TLDs around the globe allow ID Protection to be added, but there are still country-code extensions that do not support the service.
