So the new NetworkManager has the ability to do much, MUCH more than the
old on in 6.5 (which was turned off by default by me).
The IPV4 section will add as manay additional IPs as needed creating a file
like this:
TYPE=Ethernet
BOOTPROTO=none
IPADDR0=170.140.61.59
PREFIX0=24
GATEWAY0=170.140.61.2
IPADDR1=192.168.100.1
PREFIX1=24
DNS1=170.140.1.1
DNS2=170.140.2.1
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=enp0s25
UUID=f00e6346-be4c-40ce-b1db-17f926a8edba
DEVICE=enp0s25
ONBOOT=yes
HWADDR=00:26:B9:8E:73:29
Yes. ifconfig is now dead (<sob>). Must learn new tool that give craptons
of data in either pretty or terse format.
nmcli d show (give loads in terse format).

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
