Network-Set-Calculator

network-set-calculator.py is a small Python script that computes sets of IP subnets (e.g. for routing tables or WireGuard AllowedIPs settings) using include and exclude operations. The script requires Python 3 to be installed on your machine - however, it only uses the Python standard library, so it has no further dependenies.

Usage:

Launch the script using Python 3 (python, python3, or execute it directly) on your command line. Supported command-line options include:

-h, --help
    Display a help message and exit
-i INCLUDED, --include INCLUDED
    Include IP range (can be specified multiple times). If this option is never specified, 0.0.0.0/0 (all IPv4 addresses) is included
-e EXCLUDED, --exclude EXCLUDED
    Exclude IP range (can be specified multiple times)
--exclude-private-ipv4-ranges
    Exclude private/non-routable IPv4 ranges
--exclude-private-ipv6-ranges
    Exclude private/non-routable IPv6 ranges
-I OVERRIDEINCLUDED, --include-override OVERRIDEINCLUDED
    Include IP range even if it's part of an excluded range (can be specified multiple times)

The output (i.e. the final list of subnets) is printed to the console.
