 Review comment:
   I would like more specific catch clauses. catch'm'all is a bit crude (and it 
will also happen on the ApiServlet level.

>             Project: CloudStack
>          Issue Type: New Feature
>      Security Level: Public(Anyone can view this level - this is the 
> default.) 
>          Components: API
>    Affects Versions: 4.10.0.0
>            Reporter: Nitin Kumar Maharana
>             Fix For: 4.10.1.0
>
>
> At present, The management IP range can only be expanded under the same 
> subnet. According to existing range, either the last IP can be forward 
> extended or the first IP can be backward extended. But we cannot add an 
> entirely different range from the same subnet. So the expansion of range is 
> subnet bound, which is fixed. But when the range gets exhausted and a user 
> wants to deploy more system VMs, then the operation would fail. The purpose 
> of this feature is to expand the range of management network IPs within the 
> existing subnet. It can also delete and list the IP ranges.
