DNS leak tests are important because they reveal whether or not your online activity is private. Domain name system (DNS) servers translate that human web address that you type into the browser (the domain name) to computer language (the IP address). When you type an address into your device, it reaches out to the DNS to find out what number (IP address) is associated with that domain name.

Blacklists are compiled by email servers and spam filters, but there’s no central blacklist that keeps track of everyone.
