This tool is used to search for AWS IP prefixes by region or service, instead of by IP address.

It is a simple web page with an interface to search the AWS IP address ranges. It downloads the ip-ranges.json file and makes it searchable.

You can use the tool here: https://shotstack.io/tools/aws-ip-search-tool/.

The webpage and build script were built almost entirely using ChatGPT in about an hour.
