DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. Encryption by itself does not protect privacy, encryption is simply a method to obfuscate the data. As of March 2018, Google and the Mozilla Foundation started testing versions of DNS over HTTPS.
Starting with Google Chrome 78, you can enable DNS-over-HTTPS via a new Secure DNS lookups command line flag.
This tutorial will show you how to enable or disable DNS over HTTPS (DoH) in Google Chrome for your account in Windows 7, Windows 8, or Windows 10.
