To add (a) new IP address(es) to your cPanel server, use the Add a New IP Address feature in the WHM interface. This interface ensures that the IP(s) is (are) usable by the cPanel server.
The interface supports the following formats:
- Class C CIDR (e.g., 192.168.4.0/25)
- IP Address Range (e.g., 192.168.4.128-255)
If your server is using NAT (Network Addresses Translation), use the local IP, not the public IP.
If your server is NOT using NAT (Network Addresses Translation), use the public IP.
To add additional IP(s), do the following.
1. Log in to WHM.
2. Navigate to WHM: Home -> IP Functions -> Add a New IP Address.
3. Add the IP/IP ranges to text boxes using the above formats.
4. Select Submit.
