For your Chromebook to be productive and efficient, it needs to have a strong internet connection because, after all, its primary function is to browse the internet. However, you may experience a number of issues with your network connection that can slow down the internet speed on your Chromebook.
Luckily, you can fix many of these network issues with a simple, built-in solution. All you have to do is change the default DNS server on your device.
So, let’s understand what a DNS is, why changing it is beneficial, and how you can change it on your Chromebook.
What is DNS?
The Domain Name System, or DNS for short, provides a naming mechanism to identify different websites on the Internet. A request to open a web page or download a file must go through this one.
By default, your Internet Service Provider or ISP sets the DNS server, which is not always reliable. It is sometimes unable to process requests and slows down the internet. Additionally, ISPs often block access to multiple websites through their DNS.
As network requests go through the default DNS, on rare occasions these requests may contain viruses and malware as some default DNS servers are not strong enough to detect and quarantine these threats. Although this is rarely the case, most ISPs deal with this issue on their end.
Benefits of Changing DNS Servers
Big tech companies like Google, Cloudflare, Norton, AdGuard and others have their own DNS servers. These servers are fast, strong and reliable and can improve your internet connection, unblock restricted websites and enhance your privacy and security.
By changing the DNS, you can access geo-restricted content. Most DNS servers allow you to configure parental controls and filter the web according to your preferences. They also protect you from fake websites that try to hack you through malware.
How to Change the DNS on Your Chromebook
To change the DNS on your Chromebook, you just need to tinker with a few options in the settings menu. Your device uses the DNS provided by your Internet service provider by default.
Please note that before making any changes to DNS, be sure to save a screenshot of the settings or write down the default DNS address somewhere in case the DNS change causes issues on your device.
Before changing the DNS, first decide which new DNS you want to use. There are many public DNS servers available such as Google, Cloudflare, OpenDNS and many more.
Now, to switch to the DNS server of your choice, open the Chromebook settings. You can do this using one of the following methods:
- Click on the Launcherthen on the Caret icon (^) to find Settings.
- Or you can click the Time option in the lower right corner and click on the Equipment icon.
Changing DNS for a Specific Internet Connection
If you have multiple Internet connections, you may want to change the DNS for a specific connection only. To do this, go to the Network menu in the settings. The Network menu will present you with several options.
Click on the type of network you are using, such as Ethernet, Wi-Fi, or mobile network. We chose Wi-Fi, then the specific Wi-Fi the device was connected to. After that click on Network to expand the options.
In the extended Network submenu, you will see information such as IP address, name servers, and MAC address. The option you are looking for is name servers, which is another name for DNS servers.
Under Name Servers, you have three options for setting DNS. By default, the Automatic name servers are selected, which are the DNS servers provided by your ISP. The second option is Google name servers, which is the DNS provided by Google. To switch from default DNS to Google nameservers, simply select the Google name servers option. It will then change your DNS to 126.96.36.199 and 188.8.131.52.
If you want to set a custom DNS such as those provided by Cloudflare or OpenDNS, select the third option, Custom name servers. Here you can enter the DNS servers of your choice. For example, OpenDNS servers are 208.67. 222.222 and 208.67. 220.220.
Once you have added the custom values in this space, you have successfully set a custom DNS. Here is a comparison between Google DNS and Cloudflare DNS, as they are among the best providers these days.
Changing DNS for all network connections
If you don’t want to worry about changing DNS servers for each of your network connections, you can simply set a system-wide DNS server that automatically applies to each connection.
To do this, go to your Chromebook’s settings as mentioned above. In the left sidebar, click Security and privacy. Here, click on the last option that says Use secure DNS.
In this option, your ISP’s DNS is selected by default. You can change it to the DNS of your choice by clicking on the second option that says With. You can either select a predefined DNS server from the drop-down menu or enter a custom DNS.
Whichever name server you set here will work on all your internet connections. Thus, you do not have to manually modify each of the DNS servers of your connections.
Some of the best DNS servers available
To save you time looking for DNS servers, here is a list you can use.

|Neustar Ultra DNS
There are many other DNS providers that you can find with a simple Google search. Just be sure to check the vendor’s reviews before using it.
Set DNS of your choice for better browsing
DNS is important for proper network operation and privacy. It’s almost always a good idea to use reliable and fast DNS servers rather than the default ones, as this will not only help you access geo-restricted content, but also improve network latency.
If accessing blocked content on the Internet is your ultimate goal, you should consider installing a VPN instead of changing DNS on your Chromebook.
