Which Azure region is "North Central US"

I am trying to whitelist an Azure region in an app. I downloaded the IPs for the regions from here: https://www.microsoft.com/en-us/download/details.aspx?id=41653 and I do not see one that is obviously North Central US

For US, there are (in the order they appear in the download):

• uscentraleuap
• uscentral
• useast2euap
• useast2
• useast
• usnorth
• ussouth
• uswestcentral
• uswest2
• uswest

Any idea which is which? I assume either uscentral or usnorth? Some are named very descriptively, others are not...

North and South are both central. Where there are variants (like uswest, uswest2, uswestcentral) it’s because multiple data centres are present. See https://azure.microsoft.com/en-gb/global-infrastructure/regions/

You could also use this blog post about the release of that document to correlate with the IP addresses you’re seeing, as the more explicit names are used. https://blogs.technet.microsoft.com/keithmayer/2013/08/14/windows-azure-datacenter-ip-ranges/
