I would like to set my DNS server to 184.108.40.206. I followed online instructions and went to Network Connections->Wired Connection 1->Edit->Ipv4 Settings and put 220.127.116.11 into Additional DNS servers. This does put 18.104.22.168 as a secondary DNS server. I can check this using
nmcli dev show.
How can I make
22.214.171.124my primary DNS server instead?
