For a myriad of reasons it’s nice to know what IPs you can expect to see coming to/from your Azure space.  Below is a quick cheat sheet.

Microsoft Azure Datacenter IP Ranges

• Public: https://www.microsoft.com/en-us/download/details.aspx?id=56519
• US Gov (including DoD): http://www.microsoft.com/en-us/download/details.aspx?id=57063
• Germany: http://www.microsoft.com/en-us/download/details.aspx?id=57064
• China: http://www.microsoft.com/en-us/download/details.aspx?id=57062

updated 20 Aug 2018, thanks to Michael Ketchum of Microsoft for the additional information

The XML file now breaks down the IP ranges as follows:

• “<SERVICE>” = Includes all IP’s for that service across all regions in the applicable cloud
•  “<SERVICE>.<REGION>” = Includes all IP’s for that service in a specific region
•  “AzureCloud.<REGION>” = Includes all IP’s/and services for that region
•  “AzureCloud” = Includes all IP’s/and services for that cloud, such as Gov, commercial, etc.

The “Secret Azure IPs” you MUST Include – 168.63.129.16 and 169.254.169.254
