This is a response to the OP, not DJPfulio...

Or you can probably do it with the following very short minimal
shellscript run from /etc/rc.local or whatever systemd runs after
bringing up all services:

===============================================================

ip link set dev lo up
ip link set dev enp3s6 down
ip addr add 192.168.100.87/24 dev enp3s6
ip link set dev enp3s6 up
ip route add default via 192.168.100.96

===============================================================

The preceding shellscript does the job quite well, on pretty much any
distro, but it gives all sorts of warnings if it has to undo networking
done previously. 

If you want something a lot more robust, portable and universal, that
works in spite of an earlier partial or complete or erroneous network
setup,
read https://www.troubleshooters.com/linux/qemu/nobs.htm#hostnetworking .

As Russell said earlier in this thread, it's point and clickism that
got you into this "I can't remember" mess in the first place.
