Hi Guys,
This is a common issue with DirectAdmin.
Sometimes, when you restart the server or network you will find that all the dedicated IP's are missing in the panel.
That must be a frustrating situation, however the solution is very simple.
The IP's are missing because the "startips" service is down.
Start or restart the service.
/etc/init.d/startips
Also, enable this to auto start on reboot.
chkconfig startips on
That will fix the issues!
