Manage IP addresses on your WHM server

This blog will show you how to manage your existing IP’s and add new ones in WHM.

You can obtain additional IP addresses from your web host. Some will charge, while others will give them out for free.

We recommend you read this blog even if all your IP’s have been added, since we will be pointing out some other tools that might come in handy in the future.

Step 1- Locate the ‘IP functions’ category in WHM.

Step 2 – Let’s start by rebuilding the IP address pool. As stated on the page, this tool will determine if any of the IP addresses bound to your server are unused. Marking them as such will enable them to be used for other purposes.

Step 3 – Sometimes, an IP address will be incorrectly marked as in –use, running this should fix problems like that. Click ‘Proceed’. As you can see our system has 0 free IP’s.

Step 4 – But if your system has free IP’s then you can view them by clicking ‘Show or delete current IP addresses’.

Step 5- Here, you can see all your active IP addresses and the interfaces to which they are assigned. If an IP is not being used, you can remove it here.

Step 6 – Do so by clicking ‘remove’. The IP address has been successfully removed.

In order to remove an IP that is in use, you must first remove all the account’s using that IP or switch them to a new one.

Step 7 – Let’s re-add the IP we just removed. Type it here in the ‘Add an IP Address’ interface under ‘IP Functions’ category. As there is no free IP to add, you will receive following message:

Step 8 – When you receive new IP addresses from you hosting provider, they should give you the correct subnet mask to use. Without that you can’t use the addresses.

Step 9 – Ensure that the subnet mask is correct one for this IP. Note that you can enter Multiple IP addresses at once. When finished click ‘Submit’.

The IP addresses have been successfully added to the server and are ready for use. Other noteworthy tools in the ‘IP functions’ category allow you to change a site’s IP address. Show how IP’s are being used and reserve IPs for specific purposes.

You now know how to manage IP addresses on your WHM server.
