When you register a domain, you are required to give a valid address, email account and telephone number as per the policies approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, however, is not kept only by the domain name registrar, but is visible to the general public on WHOIS check web sites too, so anyone can check your details and certain people may not be pleased with that fact. As a consequence, a lot of domain registrars have come up with the so-called Whois Privacy Protection service, which hides the domain registrant’s contact details and upon a WHOIS lookup, people will see the details of the domain registrar, not those of the domain owner. This service is also called Privacy Protection or Whois Privacy Protection, but all these expressions refer to one and the same service. Currently, most of the TLDs around the world allow Whois Privacy Protection to be added, but there are still country-specific extensions that don’t support this service.
