If you are in Redhat, ~ version 7.3+, you can go to /etc/sysconfig/network-scripts/, and find a file named ifcfg-eth0 for the first hardware device, ifcfg-eth1 for the 2nd device, so on. To add a second IP/Mask/Network to eth0, you can create this file: ifcfg-eth0:1. The contents of that file can be similar to: DEVICE=eth0:1 ONBOOT=yes BOOTPROTO=static IPADDR=10.0.0.0 NETMASK=255.0.0.0 BROADCAST=10.255.255.255 D.
