When you register a domain name, you are required to supply a valid street address, email and telephone as per the policy approved by the Internet Corporation for Assigned Names and Numbers (ICANN). This information, though, is not kept only by the domain name registrar, but is available to the public on WHOIS check web sites as well, so anybody can check your information and lots of individuals may not be happy with that fact. Consequently, a lot of registrar companies have come up with the so-called ID Protection service, which hides the client’s contact information and upon a WHOIS check, people will see the details of the domain registrar, not those of the domain owner. This service is also called WHOIS Protection or Privacy Protection, but all these names refer to the very same service. Currently, most of the top-level domain names around the globe allow ID Protection to be added, but there are still country-specific extensions that do not support the service.
