When you register a domain, you are obliged to supply a genuine address, email and telephone number as per the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This info, however, is not kept only by the registrar company, but is visible to the public on WHOIS web sites as well, so anybody can view your details and a lot of people may not be okay with this. Consequently, a lot of companies have introduced the so-called Whois Privacy Protection service, which conceals the client’s contact details and upon a WHOIS lookup, 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 names refer to one and the same service. Now, most of the Top-Level Domains around the world allow Whois Privacy Protection to be added, but there are still country-code extensions that do not support the service.
