When you register a domain name, you have to supply an authentic home address, email account and phone as per the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the domain registrar, but is available to the public on WHOIS lookup sites as well, so anyone can see your information and many people may not be okay with that fact. Consequently, many companies have introduced the so-called Whois Privacy Protection service, which hides the domain name registrant’s contact details 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. As of now, most of the TLDs around the globe allow Whois Privacy Protection to be enabled, but there are still country-specific extensions that don’t support the service.
