Does this IP belong to AWS?

This repository contains helpers to determine whether an IP belongs to AWS, and if it does, which AWS service and region use it.

HTML

This helper relies on JSONata, a powerful query and transformation language for JSON. See https://jsonata.org

You can find the raw script in this repo or visit does-this-ip-belong-to-aws.terracloud.fr to see it in action!

Python script

For use in a shell, a convenient python script using only base libraries.

Example: python3 awsip.py 3.5.140.3 returns:

[
    {
        "ip_prefix": "3.5.140.0/22",
        "region": "ap-northeast-2",
        "service": "AMAZON",
        "network_border_group": "ap-northeast-2"
    },
    {
        "ip_prefix": "3.5.140.0/22",
        "region": "ap-northeast-2",
        "service": "S3",
        "network_border_group": "ap-northeast-2"
    },
    {
        "ip_prefix": "3.5.140.0/22",
        "region": "ap-northeast-2",
        "service": "EC2",
        "network_border_group": "ap-northeast-2"
    }
