We mentioned earlier that Microsoft is developing DoH support for Windows 10 systems, but it is not clear in which version it will bring this feature. The DoH function is designed to encrypt DNS query traffic from being attacked and hijacked by operators or middlemen, so using this protocol helps improve privacy and security. Although Microsoft has not natively supported this feature in Windows 10, mainstream browsers such as Google Chrome and Firefox have already been supported.
At present, there are relatively few public DNS servers that support the DoH function. Networks in different regions use these public DNS servers at different speeds. If you are interested, you can start testing to see if normal access is affected. If you can feel that the webpage loading speed is significantly slower, please switch back to your public DNS server or continue to use the operator’s default DNS server.
Google Chrome has started testing the DoT function in Google Chrome v78, so if you need to enable this feature, you need at least version 78 and above. Open the Google Chrome address bar and enter chrome://flags/#dns-over-https, and then change the option to Enabled and restart the browser.
After the browser part is modified, you need to modify the operating system’s public DNS server. Go to the Network and Sharing Center in the Windows 10 Control Panel. Then click Change adapter settings on the left to find the network card in use, right-click the network card and select Properties, then configure DNS in IPv4 / IPv6.
