subnet_it

Dynamically calculate available for further subnetting free CIDRs based on already reserved subnets/ranges and Virtual Network address spaces.

Example:

❯ python subnet_it.py
usage: subnet_it.py [-h] -s SUBSCRIPTION_ID [-v] [-f]
subnet_it.py: error: the following arguments are required: -s/--subscription_id

python subnet_it.py -s '< subscription id >' -f

Example:

❯ python network_it.py -s '< subscription id >' -a '10.0.0.0/12' --size 22 -f
