When you register a domain name, you are obliged to give a valid postal address, email and phone in accordance with 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 accessible to the general public on WHOIS lookup sites too, so anyone can view your details and certain people may not be okay with that fact. As a consequence, a lot of registrars have introduced the so-called Whois Privacy Protection service, which conceals the registrant’s contact info and upon a WHOIS check, people will see the details of the registrar, not the domain owner’s. This service is also called Whois Privacy Protection or Privacy Protection, but all these terms refer to the same service. At the moment, most of the TLDs around the world allow Whois Privacy Protection to be activated, but there are still country-code extensions that do not support this service.
