Force changing the ip of the Heroku dyno

Question

I am wondering if there is a way to reset the dyno IP on Heroku when I want.

I noticed sometimes it changes when the application is restarted. However, not always.

How can we reset the dyno IP address on restart every time?

I already saw these questions:

• Does Heroku change dyno IP during runtime?

Answer 1

It turns out by restarting the app (deleting the dynos), the IP is changed, by default.

You can do this by using the Heroku API.

This does indeed appear to work. For some reason Mailchimp blacklisted one of the IP's used by Heroku, but restarting our app must have given us a different IP for now it's no longer blocked. – Applegate
