A step-by-step tutorial to activate DNS-over-HTTPS (DoH) support in the Google Chrome browser.

You can now activate support for the privacy-based DNS-over-HTTPS (DoH) protocol in the Google Chrome browser with the help of a command-line argument.
The process is complex, but this step-by-step tutorial can assist users set up DoH support in Google Chrome, and be sure it’s functioning in a proper manner.

WHAT IS DNS-OVER-HTTPS AND HOW DOES IT FUNCTION?

DNS-over-HTTPS stands for a quite new web protocol, being used for only a couple of years.

It functions just similar to the initial DNS protocol, implying its basic aim is to take a domain name that a customer indicates in a browser and submits a query to a DNS server to identify the numerical IP address of the web server that hosts that webpage.

با این حال, while the classic DNS protocol submits this request in plaintext, for everyone to recognize it, DoH packages its DNS queries as ciphered HTTPS traffic.

The main priority of DoH is that the protocol conceals DNS requests and responses in the huge stream of HTTPS traffic that circulates across the web each second. This implies that third-party observers can’t glance at DNS requests to establish what a user could be attempting to access.

This scheme makes DoH a protocol helpful for bypassing DNS-based blocklists, as there isn’t any DNS traffic for filtering.

Mozilla Firefox has already elaborated support for the DoH protocol a couple of years ago. همین الان, activating DoH support in Mozilla Firefox is as helpful as hitting a couple of buttons.

با این حال, activating DoH in Google Chrome isn’t as simple, considering the fact that Google is nowadays slightly behind with supporting the protocol. DoH functions just great in Google Chrome, but there’s no GUI for activating or setting it up.
