When you register a domain, you are required to provide a valid address, email account and phone in accordance with the policies adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the registrar, but is visible to the public on WHOIS websites too, so anybody can view your info and many people may not be happy with that fact. As a consequence, plenty of registrar companies have introduced the so-called Whois Privacy Protection service, which hides the client’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 popular as Whois Privacy Protection or Privacy Protection, but all these terms refer to the exact same service. As of now, most of the Top-Level Domains around the globe allow Whois Privacy Protection to be added, but there are still country-specific extensions that do not support this option.
