List available IPs inside a subnet

[jkewley]

Is your feature request related to a problem? Please describe.
The CLI currently has a way to check for free IPs in a vnet by using az network vnet list-available-ips. This is very useful, but some enterprises have network architectures which would benefit from being able to specify a subnet qualifier. This was touched upon in #6876, but was closed after implementation of the vnet scope.

Describe the solution you'd like
I would like to see list-available-ips under az network vnet subnet:

az network vnet subnet list-available-ips 
                                   [--ids] #not sure if this is relevant
                                   [--name]
                                   [--vnet-name]
                                   [--resource-group]
                                   [--subscription]

This would behave as az network vnet list-available-ips does, but the IPs would be in the address space of the given subnet.

Describe alternatives you've considered
Compare ips returned from the az network vnet list-available-ips command against the subnet's address space, but I don't think the command supports paging so this may not be an option.

Any update?

the command az network vnet list-available-ips only display 4 or 5 available ips but if you check in azure portal there is more than 500 ips available... Is there some command to list available ips in a array json or similar in a subnet?

[a-nldisr]

az network vnet list |jq ".[].subnets[].addressPrefix"

jq has been my goto tool for everything that outputs json.

Still looking for a way to go over all the subscriptions, but this lists all the subnets per subscription. The problem is I have to deal with more than 1 subscription, more like a couple of dozen.
