When you register a domain, you are asked to provide a valid address, email and phone as per the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the domain registrar, but is visible to the public on WHOIS lookup sites too, so anyone can see your information and many people may not be pleased with that fact. As a result, many companies have come up with the so-called Whois Privacy Protection service, which conceals the domain name registrant’s details and upon a WHOIS check, people will see the details of the registrar, not those of the domain owner. This service is also called Privacy Protection or Whois Privacy Protection, but all these terms refer to the exact same service. As of now, most of the top-level domain names around the globe allow Whois Privacy Protection to be activated, but there are still country-specific extensions that do not support this option.
