I am trying to modify the current eth0 with nmcli

I ran this: nmcli con mod eth0 ipv4.addr 192.168.1.15/22 gw4 192.168.1.1 ipv4.dns 192.168.1.14

and now nmcli shows (two ipv4) addresses.

   inet4 192.168.1.15/22
    inet4 192.168.2.212/22

I think the original connection was DHCP... the 2.212 item listed.

So I want to change the original DHCP to a static network - how do I do that? I only want the one address not two.

So now I need to "remove" both or all and add the 1 I want as static ? how do I do that?

Thanks,

Supposing you don't need ipv6 and you are on console not having problems of loosing connectivity I would do

nmcli con mod eth0 ipv4.method manual ipv6.method ignore autoconnect yes ipv4.addresses 192.168.1.15/22 gw4 192.168.1.1 ipv4.dns 192.168.1.14 nmcli dev dis eth0 nmcli con up eth0

just tried on a CentOS 8.1 with Network Manager and configured with dhcp. HIH, Gianluca
