 Review comment:
   @nitin-maharana I'd second the idea to rename the method to 
`countIpAddressUsage()`

> 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.
