List of Amazon AWS IP Addresses for Firewall Configurations

A recent project used the fantastic iron.io platform to process background jobs (highly recommended if you need to write anything at scale). Part of the task required access back across the Internet to a server behind a firewall.

The iron.io platform runs on top of Amazon AWS so finding the IP addresses took a little bit of searching, but then I came across a forum post with a good list.
