Not sure I understand. Would this be a single network encompassing several vlans and ip ranges?

So i did a little more digging in your example, I also realized you code
has assumption that i have /24 entirely dedicated to CloudStack :)

Welcome to enterprise madness where IP space, while being internal and
free - is close guarded and restricted.

Do we have a concept of IP Pools in future versions? That is an
aggregate of smaller ip ranges that end user can group into 1 entity. So
if range x runs out of IP space, we just go to the next range and vlan
in that pool, without returning and error - "you ran out of IP space".

let space="32 - $space"
let space=³2**$space - 1²

let avail="$space - $used -1²
echo ³Available IPs = $avail"

Subject:  [API]How to check how many IPs are available in guest network

Is there a way to check how many guest IPs are available in specific
guest network?

Current cloudstack reporting is not granular enough, i could not find a
command that says listAvailableIPs or something similar.

Any help is appreciated.
