When you add IP from WHM, you may get the following message:
To add, edit, or remove IPs, please contact your server administrator.
To fix this issue, Login to your server as root and try adding the IP Address + Netmask to /etc/ips.
cat /etc/ips ip:netmask:broadcast 192.168.1.XX:255.255.255.255:192.168.1.255
After that restart the ipalias service
/etc/init.d/ipaliases restart
That’s all
We have done it!!!!
