What are udev's "consistent" networking names?

systemd udev uses uses a weird networking naming scheme.
different from the old eth0 wlan0 naming scheme.
why does systemd implement this 'enp1n0' weird naming scheme?
i don't get the point.

Can someone explain the purpose behind this?

From the horses mouth:

The point is that if you have multiple network adaptors under the original eth0, wlan0 naming scheme it wasn't always easy to be certain which device would end up which name after system boot. Not without writing your own udev rules

Under the persistent naming scheme the devices will always have the same predictable names.

It's easily disabled on any Linux
Code: [Select]
net.ifnames=0
on the kernel command line.
