When you register a domain, you are required to provide an authentic postal address, email account and telephone number as per the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the domain registrar, but is accessible to the general public on WHOIS lookup sites as well, so anybody can view your info and certain people may not be comfortable with this. As a consequence, many domain name registrars have come up with the so-called Whois Privacy Protection service, which hides the registrant’s details and upon a WHOIS check, people will view the details of the registrar company, not the domain owner’s. This service is also popular as Privacy Protection or Whois Privacy Protection, but all these expressions refer to the exact same service. At the moment, most of the TLDs around the world allow Whois Privacy Protection to be added, but there are still country-specific extensions that do not support the service.
