When you register a domain name, you have to give a valid postal address, email account and phone as per the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, though, is not kept only by the domain name registrar, but is visible to the public on WHOIS websites too, so anyone can check your info and some people may not be comfortable with that fact. As a result, many registrars have introduced the so-called Whois Privacy Protection service, which conceals the registrant’s info and upon a WHOIS lookup, people will view 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 same service. At the moment, most of the top-level domain names around the world allow Whois Privacy Protection to be added, but there are still country-code extensions that don’t support this service.
