如何正确确定Amazon AWS Heroku子网？ [英] How to properly determine Amazon AWS Heroku subnets?

问题描述

我需要能够通过防火墙访问构建在Heroku上的应用程序的服务器。不幸的是，来自Heroku的AWS实例的IP似乎有很大不同。有没有一种正确的方法来确定Heroku的AWS平台对应用程序所期望的子网？

正如这样不幸的是 - 没有一个好方法来持续获取这些信息。然而，在AWS论坛上，EC2工程师倾向于偶尔发布他们的IP范围（这里是一个最近的例子： https://forums.aws.amazon.com/ann.jspa?annID=1701 ）。

不足之处在于，但是，它需要大量的手动工作。

I need to be able to enable access through a firewall to a server for an app that is built atop Heroku. Unfortunately the IP's coming from Heroku's AWS instances seem to vary quite a bit. Is there a "correct" way of determining what subnet to expect from Heroku's AWS platform for an app?

解决方案

As unfortunate as this is -- there isn't a good way to continuously get this information. On the AWS forums, however, the EC2 engineers tend to occasionally post their IP ranges (here is a recent example: https://forums.aws.amazon.com/ann.jspa?annID=1701).

The downside to this, however, is that it requires a lot of manual work.
