When you register a domain name, you need to provide a genuine street address, email account and phone as per the policy approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, though, is not kept only by the registrar company, but is available to the general public on WHOIS web sites too, so anybody can see your details and many people may not be okay with this. As a result, many registrar companies have launched the so-called Whois Privacy Protection service, which hides the registrant’s info and upon a WHOIS check, people will see the details of the registrar, not the domain owner’s. This service is also called Whois Privacy Protection or Privacy Protection, but all these expressions refer to the very same service. Currently, most of the TLDs around the world allow Whois Privacy Protection to be added, but there are still country-code extensions that do not support the service.
