In case this helps anyone. The issue caused me a lot of pain:

- [Assign Static Egress IP](https://fly.io/docs/flyctl/machine-egress-ip-allocate/)
- [Static Egress IP Management](https://fly.io/docs/flyctl/machine-egress-ip/)

> [@Static egress IPs for machines](https://community.fly.io/t/static-egress-ips-for-machines/22004):
>
> You can now assign static egress IPs to your machines.! Although most apps don’t need it, it is useful when using services like MongoDB atlas that require allowlisting a range of IPs. You can allocate static egress IPs to your machine by running fly machine egress-ip allocate \<machine ID\>. These IPs survive machine migration and are not shared between machines. Static egress IPs for machines will cost $0.005 per hour.
