Google Chrome developers have announced plans to roll out DNS-over-HTTPS (DoH) support to Chrome web browser for Linux. 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. Chrome has already been supporting DoH on platforms like Windows, Mac, ChromeOS, and Android under a Chrome feature called “Secure DNS”” DoH was found to be only slightly slower than classic DNS and caused “”insignificant”” impact on overall Chrome performance.”
