When you register a domain, you need to supply an authentic address, email and telephone number as per the policies approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, however, is not kept only by the domain registrar, but is available to the public on WHOIS lookup websites as well, so anybody can check your information and some people may not be comfortable with that fact. Consequently, a lot of domain registrars have come up with the so-called Whois Privacy Protection service, which hides the client’s contact details and upon a WHOIS lookup, people will see the details of the registrar company, not those of the domain owner. This service is also popular as Whois Privacy Protection or Privacy Protection, but all these names refer to one and the same service. Nowadays, most of the Top-Level Domains around the globe allow Whois Privacy Protection to be activated, but there are still country-specific extensions that do not support this service.
