When you register a domain, you need to provide a valid street address, email account and phone as per the policy approved by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, though, is not kept only by the registrar, but is available to the general public on WHOIS check sites too, so anyone can see your information and many individuals may not be okay with that fact. As a result, lots of registrar companies have launched the so-called Whois Privacy Protection service, which hides the domain name registrant’s contact info and upon a WHOIS check, people will view the details of the domain registrar, not the domain owner’s. This service is also known as Whois Privacy Protection or Privacy Protection, but all these expressions refer to the same service. Nowadays, most of the TLDs around the globe allow Whois Privacy Protection to be enabled, but there are still country-code extensions that do not support the service.
