When you register a domain, you are requested to supply an authentic postal address, email and phone number as per the policy adopted by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, though, is not kept only by the registrar company, but is visible to the general public on WHOIS check websites as well, so anyone can see your info and many people may not be happy with this. As a consequence, many domain registrars have launched the so-called Whois Privacy Protection service, which conceals the client’s contact information and upon a WHOIS check, people will see the details of the registrar, 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. As of now, most of the top-level domain names around the globe allow Whois Privacy Protection to be activated, but there are still country-specific extensions that don’t support the service.
