AWS IP Address Ranges

AWS used to publish there IP ranges via their website.   A useful reference point for determining origin of cloud based accounts.   This reference has now been withdrawn but thankfully they provide mechanisms for retrieving this data.

There are a number of ways to do this via scripting and APIs, and they also provide pre-built Powershell scripts.     Here are the steps to run a quick query via Powershell

Install-Module AWSPowerShell
Set-ExecutionPolicy RemoteSigned
Import-Module AWSPowerShell
Get-AWSPublicipIPAddressRange -region {name}

For example to determine the ranges used by eu-west-2 region
