When you register a domain, you are requested to provide a genuine postal address, email and telephone as per the policy adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the domain name registrar, but is visible to the general public on WHOIS sites as well, so anyone can view your information and some people may not be happy with that fact. As a result, lots of registrar companies have come up with the so-called Whois Privacy Protection service, which hides the domain registrant’s contact info and upon a WHOIS check, people will see the details of the registrar company, not those of the domain owner. This service is also called Whois Privacy Protection or Privacy Protection, but all these terms refer to the exact same service. At the moment, most of the top-level domain names around the world allow Whois Privacy Protection to be enabled, but there are still country-code extensions that do not support this option.
