I've read the docs, and can't find anything about importing the data. I don't know how DHCP works, so I'm asking.... Isn't it possible to get the DHCP scopes for a subnet from the DHCP server with some sort of query? Or do we simply get this information from the DHCP server admin, and manually add the scope into the subnet and IP display?
You cannot do a query to get the DHCP scopes. You will need to get them from the admin and add them manually to IPplan.
