Example if you wanted to add aliases to eth0

Just copy /etc/sysconfig/network-scripts/ifcfg-eth0 to
/etc/sysconfig/network-scripts/ifcfg-eth0:1

Change the necessary settings in ifcfg-eth0:1 and start the dev: ifup
eth0:1

If you need more just continue to add aliases eth0:2, eth0:3, etc....

You can add them without adding the additional files, but of course if
you have to reboot you will have to re-enter them again.

Too add:
ip addr add 192.168.1.20/24 dev eth0 label eth0:1

or

ip addr add 192.168.1.20/24 broadcast 192.168.1.255 dev eth0 label
eth0:1


To delete:
ip addr del 192.168.1.20 dev eth0 label eth0:1


You can see the options to the "ip" command with:
ip help or ip <COMMAND> help
