When you register a domain name, you need to supply a valid postal address, email and telephone in accordance with the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the domain name registrar, but is visible to the general public on WHOIS lookup websites as well, so anyone can view your info and a lot of individuals may not be happy with that fact. As a result, a lot of companies have launched the so-called Whois Privacy Protection service, which conceals the client’s contact details and upon a WHOIS check, people will see the details of the registrar company, not those of the domain owner. This service is also called Privacy Protection or Whois Privacy Protection, but all these names refer to the very 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 do not support the service.
