When you register a domain, you have to supply a valid street address, email and phone number as per the policies approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, however, is not kept only by the registrar company, but is available to the public on WHOIS check sites as well, so anybody can see your info and some individuals may not be delighted with that fact. As a result, numerous registrars have launched the so-called Whois Privacy Protection service, which conceals the registrant’s information and upon a WHOIS check, 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 names refer to the same service. Today, most of the TLDs around the world allow Whois Privacy Protection to be enabled, but there are still country-specific extensions that don’t support the service.
