azure-cdn-ips's Introduction

azure-cdn-ips

This repository contains 4 files that are updated weekly based off of the contents from the Azure CDN Edge Nodes List. Azure decided that this IP list should be behind authentication instead of publicly available compared to Azure IP Ranges and Service Tags

edgenodes.json - raw JSON pulled from the Azure API
edgenodes-ipv4.txt - parsed, sorted, and unique IPv4 subnets
edgenodes-ipv6.txt - parsed, sorted, and unique IPv6 subnets
lastrun - date the script last ran

The bash script that updates this repository is located in get-azure-cdn-ips

Usage

You should not use this list to directly feed a firewall without doing your own validation.

Notes

The bash script that runs is very basic but it does have a few simple protections built into it to ensure bad data doesn't get updated to this repoistory. Time will tell if they are enough.

If we can't authenticate to the API or Azure returns an error, the script aborts
If the IPv4 list doesn't contain a subnet at the start or end of the list, the script aborts.

Edge Nodes List API Not Returning Proper Data

Since my last run on Sunday 1/10/21 the Azure API is not returning proper results. Currently its missing the data contained in the ipAddressGroups. I've opened a ticket with Microsoft to figure out why and hopefully get it resolved

  "value": [
    {
      "id": "/providers/Microsoft.Cdn/edgenodes/Standard_Verizon",
      "type": "Microsoft.Cdn/edgenodes",
      "name": "Standard_Verizon",
      "properties": {
        "ipAddressGroups": []
      }
    },
    {
