When you register a domain name, you are obliged to supply a genuine address, email and telephone as per the policy approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, though, is not kept only by the domain name registrar, but is visible to the public on WHOIS sites too, so anybody can check your info and many people may not be okay with that fact. As a result, a lot of domain registrars have launched the so-called Whois Privacy Protection service, which conceals the registrant’s contact details and upon a WHOIS check, people will see the details of the registrar, not the domain owner’s. This service is also called Privacy Protection or Whois Privacy Protection, but all these expressions refer to the very same service. Currently, most of the Top-Level Domains around the globe allow Whois Privacy Protection to be enabled, but there are still country-code extensions that do not support the service.
