how do I just remove the single ADDRESS I added as an alias ? not the whole

thing ?

You first remove all ipv4.addresses and then add the one you want. Then you save/activate.

under CentOS 7 - I use "alias" like eth1:0 for an alias network. Remove the file restart network - and back to normal. Now I am trying to us NetworkManager.

I can 'add' the network fine. however - when I remove the network nmcli connection delete "Wired connection 2" ipv4.addr 192.168.1.58/22

it remove BOTH address and removes the "Wired connection 2" config file - and it reverts to DHCP not the other static address I had associated with "Wired connection 2".
