Enabling DNS Over HTTPS in Google Chrome

Enabling DNS over HTTPS in Google Chrome is pretty easy! Google Chrome does support this feature but not enabled by default, and still you can enable and experiment it.

What's the main benefit for enabling this DNS over HTTPS feature in Google Chrome? Simply put, it will improve the privacy and security when you use this web browser for accessing different websites.

Let's talk little bit more here. As you know normal DNS queries, such as google.com you type in web browser is sent in plain text to DNS server, so that DNS server can translate it to IP address of web server and send the traffic to that destination server before your browser receive the data and display them. This plain text query data can be sniffed and captured easily by Internet service provider or other bad guys for web traffic tracking or malicious purposes.

With DNS over HTTPS feature enabled in Google Chrome, still the DNS queries will work as usual but the query data will be encrypted and cannot be sniffed by others. This makes your web surfing activity more private and secure.

Without further ado, let's follow these step by step instructions to do it.

1) Launch Google Chrome web browser, type or copy these text into the address bar and press Enter.

chrome://flags/#dns-over-https

2) You will be shown different experiment features which you can enable and test out. Go ahead to enable Secure DNS lookups feature as shown below. Please note your change will only take effect after relaunching the web browser, so go ahead to relaunch it.

3) After making change in web browser, you need to make sure the configured DNS servers on your computer support this DNS over HTTPS feature too for it to work. If not sure, you can configure the DNS over HTTPS supported DNS servers from Cloudflare (1.1.1.1 or 1.0.0.1) or Google (8.8.8.8 and 8.8.4.4) as your DNS servers.

Note: You can also find out other DNS servers with DNS over HTTPS feature support here.

4) Once it's done, you can check to see if DNS over HTTPS is working in Google Chrome by visiting Cloudflare’s Browsing Experience Security Check. You can simply do the test by clicking the Check my Browser button and see whether “Secure DNS” is enabled.
