@Steve Rice I understand that you want to whitelist the IP addresses for Blob Storage in Azure Gov on your firewall. Please correct me if I am misunderstanding.
A JSON list of IP addresses and their associated service can be downloaded from Microsoft. A list of all the possible Storage IP addresses can be found here. This file is updated weekly. New ranges appearing in the file will not be used in Azure for at least one week. Please download the new json file every week and perform the necessary changes at your site to correctly identify services running in Azure.
Hope this helps! Let us know if you run into any issues or have questions.
