When you register a domain name, you are obliged to give a valid home address, email account and telephone number as per the policies adopted by ICANN, the Internet Corporation for Assigned Names and Numbers. This information, however, is not kept only by the domain name registrar, but is accessible to the general public on WHOIS check web sites too, so anybody can view your info and many people may not be okay with that fact. Consequently, lots of domain name registrars have introduced the so-called Whois Privacy Protection service, which hides the 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 known as Whois Privacy Protection or Privacy Protection, but all these names refer to the same service. Now, most of the top-level domain names around the world allow Whois Privacy Protection to be activated, but there are still country-specific extensions that don’t support this option.
