Google announced plans to implement DNS-over-HTTPS (DoH) in the next version of its browser, Chrome 78 with users given the option of choosing the corresponding DoH server to use for DNS resolution.
This is coming on the heels of Mozilla's enabling of DoH in the main Firefox browser release for a small percentage of its users, and promise of subsequently making it available for all Firefox users. While the actual support for DoH was added to Firefox 62 to improve the way the browser interacts with DNS, using encrypted networking to obtain DNS information from the server that is configured within the browser.
Albeit, Mozilla is been criticized for enabling the feature by default on Firefox and domiciling all the DNS traffic to Cloudflare.
Google, on the other hand, is towing a different part, as it will first check whether a user's DNS provider is on its list of known DoH-compatible providers, which if the user's DNS provider is on the list, will automatically upgrade Chrome DoH to that provider's DoH server for DNS resolution.
And Chrome DoH will run on all platforms other than Linux and iOS, including Android 9 and later, which if the user has configured a DNS-over-TLS provider, Chrome will also use that instead of the ones from their list, except there is an error.
The upgrading of DNS Resolution to DoH will happen according to the user's current DNS provider, that given that it is supported, as Google feels that the users DNS resolution experience will need to remain the same.
Nonetheless, DNS-over-HTTPS (DoH) have not been welcomed in enterprise environments, governments and ISPs, as some ISPs in certain countries block connection to sites via monitoring the DNS traffic.
It will allow users to bypass such censorship or spoofing attacks and increase privacy as the DNS requests would be hard to monitor. And just anyone, including privacy advocates would be able to bypass traffic filters set in place by rogue governments to track the citizens.
