When you register a domain, you are obliged to provide a valid street address, email account and phone number in accordance with the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, though, is not kept only by the registrar company, but is accessible to the public on WHOIS lookup web sites as well, so anybody can check your details and lots of people may not be okay with this. As a result, numerous domain registrars have come up with the so-called Whois Privacy Protection service, which hides the domain name registrant’s contact information and upon a WHOIS check, people will see 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 expressions refer to the same service. Now, most of the Top-Level Domains around the world allow Whois Privacy Protection to be added, but there are still country-specific extensions that don’t support the service.
