Changing DNS server settings on Ubuntu ( Google DNS @ GDNS )
- In the System menu, click Preferences, then click Network Connections.
- Select the connection for which you want to configure Google Public DNS. For example:
- To change the settings for an Ethernet connection, select the Wired tab, then select your network interface in the list. It is usually called eth0.
- To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network.
- Click Edit, and in the window that appears, select the IPv4 Settings tab.
- If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it.
- In the DNS servers field, enter the Google Public DNS IP addresses, separated by a space: 18.104.22.168 22.214.171.124
- Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation.
- Test that your setup is working correctly
