I just want to inform you that you also can have multiple IPv4 addresses
assigned to the same interface without using aliases (eth0:x).

The command ifconfig is regarded somewhat obsoleted on linux and it is
preferred to use the command "ip".

Add many IPv4 addresses to eth0 (also works with IPv6 adresses):
ip addr add 192.168.0.1/24 dev eth0
ip addr add 192.168.0.2/24 dev eth0
ip addr add 192.168.0.3/24 dev eth0
... And so on

Delete IP addresses with "ip addr del 192.168.0.2/24 dev eth0" and so on.

"ip addr" will list addresses assigned to all interfaces.

"ip" can also be used to configure links, tunnels, routes and so on.
