Overview
This is where I'm putting my various quick-and-dirty utilities for working with the cloud.
Right now there's just one: a tool for filtering the AWS IP ranges JSON file.
You can get a filtered ip-ranges.json file or flat list of CIDR blocks without charge.
If you want your files to update automatically, you can pay $20 to keep them up to date for 5 years.
Check out the filtering tool here.
