How to configure custom DNS on Linux?


This guide will show you how to edit, add, or remove the DNS settings on your Linux device.

Changing the DNS on your device can be helpful if you're looking to improve the connection quality and, in some cases - the speed.

1. Firstly, open the terminal with the CTRL + ALT + T combination and type in the following commands:

sudo rm -r /etc/resolv.conf

sudo nano /etc/resolv.conf

2. You will be asked for your root password after each command line, just type it in and press Enter. When the text editor opens, you will have to type in these lines:

nameserver 208.67.222.222

nameserver 208.67.220.220

3. Now close and save the file by clicking Ctrl + X and pressing Y.

4. After that, please type in one last command in the terminal and press Enter:

chattr +i /etc/resolv.conf

sudo chattr -f +i /etc/resolv.conf

5. Lastly, restart your Linux device.
