How to add multiple IP addresses manually?

There are cases where one has to bind multiple ip address to same ethernet card, here are some steps to add them into your network configuration.

# ifconfig

will output all the configured addresses. For example:

eth0: inet addr:10.10.10.10 Bcast:10.10.10.255 Mask:255.255.255.0
...... and more information.

To add on extra IP addresses type:

# ifconfig eth0:1 11.11.11.12 netmask 255.255.255.0

for additional IP addresses, make sure you increment the 1 in eth0:1, for example, a third IP address (third one including your BASE IP) would be added:

# ifconfig eth0:2 11.11.11.13 netmask 255.255.255.0

Hope it helps anyone struggling!
