When you register a domain, you need to supply a valid postal address, email and phone in accordance with the policy approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, however, is not kept only by the registrar, but is accessible to the public on WHOIS websites too, so anyone can see your details and many people may not be happy with that fact. As a result, a lot of registrar companies have introduced the so-called Whois Privacy Protection service, which hides the client’s info and upon a WHOIS check, people will see the details of the domain registrar, not those of the domain owner. This service is also called Whois Privacy Protection or Privacy Protection, but all these expressions refer to the very same service. As of now, most of the TLDs around the globe allow Whois Privacy Protection to be added, but there are still country-code extensions that don’t support the service.
