How to start IPs on the server if they are assigned but not working

There are instances when additional IPs are assigned to a certain server but they still do not ping or respond, and only the main IP of the server pings. For cPanel based servers you will find them assigned at below link as well :

WHM –> IP Functions –> Show IP Address Usage

You can verify the IPs on shell using below command to see if they are attached to the virtual network interfaces are not :

# ifconfig -a

Now if you find that additional IPs are not appearing , then you can make them available using below command :

# service ipaliases start

For cPanel based servers such additional IPs are listed at /etc/ips
