Convert CIDR ranges into the ranges allowed by AWS WAF IP Sets

Workshop for demonstrating AWS WAF usage

Enhance Amazon CloudFront Origin Security with AWS WAF and AWS Secrets Manager

This project creates two regional WAF IP sets and automatically updates them with AWS service's IP ranges from the ip-ranges.json file. The ranges are configurable as well as the regions for EC2 ranges. Use cases include allowing CloudFront requests, Route53 health checker and EC2 IP range (which includes AWS Lambda and CloudWatch Synthetics).
