When you register a domain, you have to supply a valid postal address, email account and phone in accordance with 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 check websites as well, so anybody can view your info and many people may not be comfortable with this. As a result, a lot of registrar companies have introduced the so-called Whois Privacy Protection service, which conceals the client’s info and upon a WHOIS lookup, people will see the details of the 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 top-level domain names around the world allow Whois Privacy Protection to be added, but there are still country-code extensions that don’t support this option.
