You can now enable support for the privacy-focused DNS-over-HTTPS (DoH) protocol in Google Chrome using a command-line argument.
The procedure is complicated, but this step-by-step guide can help users set up DoH support in Chrome, and make sure it's up and running correctly.
WHAT IS DNS-OVER-HTTPS AND HOW DOES IT WORK?
DNS-over-HTTPS is a relatively new web protocol, being around for only two years.
It works just like the original DNS protocol, meaning its main purpose is to take a domain name (e.g. zdnet.com) that a user types in a browser and send a query to a DNS server to learn the numerical IP address of the web server that hosts that website.
But while the classic DNS protocol makes this request in plaintext, for everyone to see, DoH packages its DNS queries as encrypted HTTPS traffic.
The primary benefit of DoH is that the protocol hides DNS requests and responses in the giant stream of HTTPS traffic that moves across the internet each second. This means third-party observers can't look at DNS requests to guess what a user might be trying to access.
