View current Network Adapters by running ls ifcfg*

Additional IPs on the server displays as “ifcfg-eth0:0”, “ifcfg-eth0:1”,
To add an additional IP please run the command cp ifcfg-eth0 ifcfg-eth0:0
Edit the ifcfg-eth0:0 configuration file by running vi ifcfg-eth0:0
On the configuration file edit to change the “IPADDR” value to the new IP address and the “DEVICE” value to eth0:0
Save the changes and exit the editor
For changes to take effect and the IP to be recognized within the network run the following command
/etc/init.d/network restart
