A demo repo containing some examples of parsing APIs to solve a networking problem.

This demonstration is to show how network professionals can solve a common problem, but use modern automation techniques in order to solve it. The idea is that you learn concepts but working towards an outcome, which hopefully helps you retain the knowledge.

The problem is as a firewall administrator, you might need to find out all the allowed public IP prefixes for a cloud service, so that only those explicit ranges can be added to your firewall policy.

This may come to you in the form of a following business requirement:

The problem is, where is that public IP range(s) defined? How often does it change? How do I know when it has been updated, so I can updated my firewall rule(s)?

This demo will show you how to use automation on how to retrieve and parse this information.

The proposed workflow for the solution is documented in WORKFLOW.md

This demonstration is only supported on:

• Python 3.6 or greater
• Linux/unix machines only

There are two methods for installing or operating the demo. The instructions for each method are described below.
