When you register a domain, you are asked to give a valid address, email account and phone number as per the policies approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This info, though, is not kept only by the registrar, but is accessible to the general public on WHOIS check sites as well, so anyone can see your details and many individuals may not be comfortable with that fact. As a result, a lot of domain registrars have come up with the so-called Whois Privacy Protection service, which hides the domain name registrant’s info and upon a WHOIS lookup, people will see the details of the domain registrar, 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 world allow Whois Privacy Protection to be activated, but there are still country-specific extensions that don’t support the service.
