Multi-Cloud IP Range Firewall Matrix

Cloud providers publish the IP ranges their services use — and your firewall wants them in a very different shape. Pick a provider, service, and region below and get the matching CIDR blocks as a plain list, a JSON array, or a ready-to-paste Terraform security-group ingress block. Bundled snapshot:10,789 blocks across AWS (EC2, S3, AMAZON), GitHub (actions, hooks, git), and Google Cloud core regions.
