When you register a domain, you need to provide an authentic 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 accessible to the public on WHOIS check sites too, so anyone can check your details and many individuals may not be OK with this. As a consequence, numerous registrars have launched the so-called Whois Privacy Protection service, which hides the domain registrant’s contact info and upon a WHOIS check, people will view the details of the registrar company, not those of the domain owner. This service is also popular as Whois Privacy Protection or Privacy Protection, but all these names refer to the same service. Now, most of the Top-Level Domains around the world allow Whois Privacy Protection to be activated, but there are still country-code extensions that do not support this option.
