When you visit a new website, your computer probably submits a request to the domain name system (DNS) to translate the domain name (like arstechnica.com) to an IP address. Currently, most DNS queries are unencrypted, which raises privacy and security concerns. Google and Mozilla are trying to address these concerns by adding support in their browsers for sending DNS queries over the encrypted HTTPS protocol.
But major Internet service providers have cried foul. In a September 19 letter to Congress, Big Cable and other telecom industry groups warned that Google’s support for DNS over HTTPS (DoH) “could interfere on a mass scale with critical Internet functions, as well as raise data-competition issues.”
