Google Chrome developers have announced plans to roll out DNS-over-HTTPS support to Chrome web browser for Linux.
Yesterday, the open-source Chromium project which powers the Google Chrome web browser announced plans to release a Chrome for Linux version with DNS-over-HTTPS support.
Since 2020, Google Chrome has already been supporting DoH on platforms like Windows, Mac, ChromeOS, and Android under a Chrome feature called "Secure DNS.".
DoH encrypts regular DNS traffic over HTTPS with both DNS requests and responses being transmitted over port 443, making the traffic blend right in with regular traffic to HTTPS websites.
The web browser's built-in DNS client had been left disabled on Linux implementation for years because Chrome did not honor advanced Linux DNS configuration via the Linux Name Service Switch configuration file, explains Chromium developer Eric Orth in the document.
To make Chrome's built-in DNS resolver work smoothly with Linux, Chrome needs to read and parse Linux DNS configuration to be able to disable DoH on unsupported configurations.
