In this tutorial I’ll be demonstrating how to change Fedora 23’s DNS to Google DNS. And also how to turn off ipv6.

Personally, for me, I found it difficult to find a simple tutorial and was astonished at how simple it really was.

Step 1. Change NetworkManager

$ cd /etc/NetworkManager/system-connections/ 

There should be one file in there. I have one named “fedora” so open it using vim

$ sudo vim fedora 

Step 2. Edit the file to match these settings

So once you open the file scoll down to the [ipv4] and make it match the following


And lastly disable ipv6 by scolling down to [ipv6] and make it match the following also


Restart the network

$ sudo systemctl restart network

One more thing! Make sure DNS > Automatic is turned off!

dns fedora
