IP Range for GovCloud Workers Inside MuleSoft

The Public IP Address range that MuleSoft's Anypoint Platform for APIs & CloudHub and ‌GovCloud uses is implemented on top of Amazon Web Services' Public IP network. The range of public IP's are published via AWS for API queries.
 
Since ‌IP ranges are dynamic and may be changed in the future, exact ranges are not published by MuleSoft. We do include details on how to get the information about the IP range in the documentation here.

However, AWS documents the current ranges here: http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html. You may refer to the ip-ranges.json file located in AWS's documentation.
