When you register a domain, you are obliged to provide 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, though, is not kept only by the domain registrar, but is visible to the general public on WHOIS check websites as well, so anyone can view your details and many people may not be comfortable with this. Consequently, lots of companies have launched the so-called Whois Privacy Protection service, which hides the registrant’s information and upon a WHOIS lookup, people will see the details of the registrar, not those of the domain owner. This service is also called Privacy Protection or Whois 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 enabled, but there are still country-specific extensions that don’t support this service.
