When you register a domain, you are requested to supply an authentic street address, email account and phone 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 registrar, but is visible to the general public on WHOIS check websites too, so anyone can see your information and certain individuals may not be comfortable with this. As a consequence, many domain name registrars have launched the so-called Whois Privacy Protection service, which hides the domain registrant’s information and upon a WHOIS check, people will see the details of the domain registrar, not those of the domain owner. This service is also known as Whois Privacy Protection or Privacy Protection, but all these expressions refer to the exact same service. Now, most of the TLDs around the world allow Whois Privacy Protection to be added, but there are still country-specific extensions that don’t support this option.
