Changing the DNS settings on a Chromebook is a practical step for users who want to enhance their online privacy, bypass regional restrictions, or troubleshoot specific network issues. The Domain Name System acts as the internet's phonebook, translating human-friendly domain names into numerical IP addresses your device uses to connect to websites. While your Internet Service Provider automatically assigns a default DNS, switching to a public resolver like Google DNS or Cloudflare can improve security and sometimes increase connection speed.
Before you begin the configuration, it is important to understand that Chromebooks primarily manage networks through the settings menu, but advanced options require access to the underlying Linux (Beta) environment or the legacy Crostini container. The process differs slightly depending on whether you are using a personal account, a managed work or school account, or if you have developer mode enabled. Most standard users will find the necessary settings within the standard Chrome OS interface without needing to enable Linux at all.
Preparing to Change the DNS
To avoid losing your current network configuration, it is wise to note your current settings before making changes. This allows you to revert back instantly if the new DNS does not perform as expected. You should also determine which network you are actively using, as the settings apply per connection rather than globally across the device.
Checking your current connection
Begin by clicking the time in the bottom right corner of your screen to open the Quick Settings panel. Select the connected Wi-Fi or Ethernet icon to open the network details. Here, you can see the name of the network you are joined to, which is necessary for targeting the correct configuration later in the process.
Modifying DNS via the Chrome OS Settings
The most straightforward method uses the standard Chrome OS settings menu, which guides you through the steps without requiring deep technical knowledge. This interface handles the heavy lifting of editing configuration files and is the recommended approach for everyday users looking to switch to services like 1.1.1.1 or 8.8.8.8.
Step-by-step configuration
Follow these steps to manually assign a DNS server:
Open the Settings app by clicking the time area or selecting the gear icon in the system tray.
Navigate to Network & Internet , then click on Wi-Fi or Ethernet depending on your connection type.
Select the specific network you are currently using or plan to use in the future.
Scroll down and click on Name servers .
Select the option for Custom and enter the preferred and alternate DNS addresses provided by your chosen provider.
Click Save to apply the changes immediately.
Using Google and Cloudflare Public DNS
Two of the most popular and reliable services are Google Public DNS and Cloudflare DNS, both of which offer free global resolution with strong performance records. Choosing between them often comes down to slight differences in latency or adherence to privacy policies, though the average user will find negligible differences in everyday browsing.
