How likely is it that an IP for an app to change?

I’m planning to have customers point domains at app IP addresses with A records, and it would be a problem if the IPs were to ever change.

It’s best to tell you users to point to you using a CNAME when possible.

Public IPs are guaranteed not to change for your app for as long as it’s not-deleted and you’re paying your bill :slight_smile: (or of course, if you remove the IPs from your app).
