Ip Ranges

Sometimes it's useful to know what IP ranges our servers are operating in. Since we run on Heroku, it's a little complicated. However, Heroku runs on AWS, which has this page dedicated to IP Ranges by Region.

Heroku recommends using this to identify which region are bing in use. If dynos are run in common spaces in US region, we can look up information about this region using Heroku's API:

using httpie:

 http https://api.heroku.com/regions/us "Accept:application/vnd.heroku+json; version=3"
