When you register a domain, you are obliged to supply an authentic postal address, email and telephone as per the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, though, is not kept only by the domain name registrar, but is accessible to the general public on WHOIS check web sites too, so anyone can view your information and some individuals may not be comfortable with this. As a result, a lot of companies have come up with the so-called Whois Privacy Protection service, which hides the client’s details and upon a WHOIS lookup, people will see the details of the registrar company, not the domain owner’s. This service is also known as Privacy Protection or Whois Privacy Protection, but all these terms refer to the exact same service. Now, most of the TLDs around the globe allow Whois Privacy Protection to be enabled, but there are still country-specific extensions that do not support the service.
