Yes, IIRC this is referred to as aliasing.

Generally you can implement this old-style by going 'ifconfig eth0:1'

'ifconfig -a' will then list a new interface called 'eth0:1'.

Each distro will have its own preferred way to store such a config, though.

It's also possible to rename interfaces, though generally it's not
worth bothering.
