When you register a domain, you are obliged to give a genuine address, email and phone number as per the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, however, is not kept only by the registrar, but is accessible to the general public on WHOIS check sites as well, so anyone can see your details and many people may not be OK with that fact. Consequently, plenty of registrar companies have introduced the so-called Whois Privacy Protection service, which hides the domain registrant’s info and upon a WHOIS lookup, people will view the details of the domain registrar, not the domain owner’s. This service is also called Privacy Protection or Whois 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 do not support this option.
