When you register a domain, you are asked to give a genuine postal address, email and phone number as per the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the domain registrar, but is accessible to the public on WHOIS check websites too, so anybody can view your info and some people may not be okay with that fact. Consequently, lots of domain registrars have come up with the so-called Whois Privacy Protection service, which hides the domain registrant’s information and upon a WHOIS lookup, people will see the details of the registrar, not those of the domain owner. This service is also known as Whois Privacy Protection or Privacy Protection, but all these terms refer to the same service. At the moment, most of the top-level domain names around the world allow Whois Privacy Protection to be activated, but there are still country-code extensions that don’t support this option.
