DNS stands for Domain Name System and makes it as it can type google.com instead of 22.214.171.124. What DNS does is map the URL you type in to the correct IP address associated with the address. In the example I just mentioned, 126.96.36.199 is one of the IP addresses mapped to google.com.
Without DNS, you would have to remember IP addresses, which is not user-friendly.
By default, DNS is not very secure. Every time you perform a search in your web browser, that search is sent in plain text. This means anyone intercepting the search data you send from your Chromebook can be read. However, if you’re using secure DNS, this lookup data is encrypted, so it’s much harder to read. Because it’s so easy to enable secure DNS in ChromeOS, it should be considered a must for anyone adamant about security and privacy.
How to Enable Secure DNS on Your Chromebook? I’ll show you how.
Luckily, Google actually built this into ChromeOS, so all you need to do is enable it, then select a DNS service that supports secure DNS. I’m going to do this using Cloudflare’s DNS service 188.8.131.52, which is free.
I will demo on ChromeOS 103.0.5045.0. Let’s get to work.
Enable Secure DNS on ChromeOS
- Log in to your Chromebook and click on the system tray at the bottom right of your screen.
- From this window (Figure 1), click the gear icon to open the Settings app.
3. In the resulting window (Figure 2), click Security & Privacy.
4. In the Security & Privacy section (picture 3), you will see the Use secure DNS option.
5. Click the ON/OFF slider for Use secure DNS until it is in the ON position.
5. Once Secure DNS is enabled, check the With box, then select Cloudflare 184.108.40.206 from the drop-down menu (Figure 4).
You can then close the Settings app, open Chrome, and start browsing to your heart’s content, knowing that your DNS queries will be sent over a secure connection. Congratulations, you’ve added a new layer of security to your Chromebook.
