Available Subnet Finder

With a fragmented IP subnet listing, it can be difficult to find larger contiguous blocks to assign to sites, especially if you have multiple sources of truth. This script is designed to provide a way to find available subnets within a given supernet. For example, if you want to find all the available /19 networks available within your 10.0.0.0/8 space, you could feed this subnet all your known networks, and it will give you subnets which are not used.

This can be used as a module to another Python script, or independently.

Help available on within the interactive shell via help() or via cli via -h.
