Each time you visit a website, your browser interacts with a domain name system (DNS) resolver that converts web addresses to an IP address understood by the machines along your path. Historically however this traffic exchange isn’t encrypted, making it possible for your broadband provider or another third party to monitor your browsing data based on your DNS queries. DNS inventors in the 80s didn’t really bet on a future where all DNS queries would be tracked, monetized, or weaponized by third parties.
