Programmatically get Amazon IP Ranges/CIDRs

Amazon Internet Companies (AWS) operates an intensive community infrastructure with an unlimited variety of IP addresses and CIDR blocks. As a developer or community administrator, you might have to programmatically retrieve the IP ranges or CIDRs related to AWS areas and companies for numerous causes, comparable to configuring firewall guidelines or community safety teams. On this information, we’ll present you how one can accomplish this utilizing Python.

Stipulations

Earlier than we dive into the code, be sure you have the next stipulations in place:

• Python put in in your machine.
• The requests library for making HTTP requests. You’ll be able to set up it utilizing pip:

Python Code to Fetch AWS IP Ranges

We will use the official AWS IP Deal with Ranges service to acquire the IP ranges and CIDRs related to AWS areas and companies. AWS supplies this info in JSON format by a publicly accessible URL. Right here’s a Python script that fetches and parses these IP ranges:

import requests

# URL for AWS IP ranges JSON information
url = "https://ip-ranges.amazonaws.com/ip-ranges.json"

# Ship an HTTP GET request to fetch the JSON information
response = requests.get(url).json()

# Initialize an empty record to retailer IP prefixes for a particular area (e.g., eu-central-1)
uae = []

# Iterate by the 'prefixes' key within the JSON response
for i in response['prefixes']:
    if i['region'] == 'eu-central-1':
        uae.append(i['ip_prefix'])

# Print the overall variety of IP prefixes and the record of IP prefixes for the area
print("Complete IP Prefixes:", len(uae))
print("IP Prefixes for eu-central-1:", uae)

On this code:

• We use the requests library to ship an HTTP GET request to the AWS IP Deal with Ranges service.
• We parse the JSON response and extract the IP prefixes for the 'eu-central-1' area for example.

Operating the Script

To run the script:

1. Copy the code right into a Python file (e.g., get_aws_ip_ranges.py).
2. Open a terminal or command immediate.
3. Navigate to the listing containing the script.
4. Run the script utilizing the python command:

python get_aws_ip_ranges.py

The script will fetch and show the overall variety of IP prefixes and the record of IP prefixes for the required area. You’ll be able to modify the script to focus on different areas or companies by altering the area code within the if situation.

Instance output

Complete IP Prefixes: 290
IP Prefixes for eu-central-1: ['52.93.244.0/24', '52.219.170.0/23', '52.219.168.0/24', '52.93.126.135/32', '13.34.73.96/27', '16.12.32.0/22', '142.4.161.168/29', '16.12.24.0/21', '3.5.136.0/22',

Conclusion

Programmatically fetching AWS IP ranges and CIDRs may be helpful for managing community safety, firewall guidelines, and different network-related duties. With the offered Python script, you may simply retrieve this info and combine it into your infrastructure and safety insurance policies.

For extra particulars on AWS IP ranges and to remain up-to-date with modifications, seek advice from the official AWS IP Deal with Ranges documentation.
