As Michael pointed out, you don’t.

Instead, you add additional Address= and Gateway= lines to the interface.

Example:

$ cat /etc/systemd/network/eth0.network
[Match]
Name=eth0

[Network]
Address=2a0a:3840:1337:126::b9c1:7ecb:1337/64
Gateway=2a0a:3840:1337:126::1
IPv6AcceptRA=no

Address=185.193.126.203/24
Gateway=185.193.126.1

DNS=95.215.19.53

[DHCP]
UseDNS=false

You don't. Interface aliases don't exist anymore.

@MichaelHampton Thanks Michael, so how can I add another IP to eth0 then? I am trying to solve serverfault.com/questions/1029000/….

I need to create a persistent network bridge for Virtual machines ( libvirt ) So this bridge does not need any physical ports, connections will be routed for this bridge.

Predictable Network Interface Names

So, I've been looking into this systemd "Predictable Network Interface Names" for quite some time and got some understanding on how it works, but I can't for the love of Thor figure out the naming scheme with enp X s Y , I know that it's supposed to indicate the physical location of the device, but what exactly does the X and Y mean?
