Configure multiple ip address on a single nic

Configure multiple ip address on a single nic

   
 Setting up 2 IP address on single NIC.

    STEP 1 (The settings for the initial IP address)

          $ cat /etc/sysconfig/network-scripts/ifcfg-eth0

           DEVICE=eth0
           BOOTPROTO=static
           BROADCAST=192.168.99.255
           IPADDR=192.168.1.155
           NETMASK=255.255.252.0
           NETWORK=192.168.1.0
           ONBOOT=yes

    STEP 2 (2nd IP address: )

          $ cat /etc/sysconfig/network-scripts/ifcfg-eth0:1

           DEVICE=eth0:1
           BOOTPROTO=static
           BROADCAST=192.168.99.255
           IPADDR=192.168.1.182
           NETMASK=255.255.252.0
           NETWORK=192.168.1.0
           ONBOOT=yes

The same way you can create multiple file like ifcfg-etho:x for multiple ip addressess,  where x can be upto 16 recommended.
