Hi Railway Team,

I wanted clarification regarding Railway networking and static IP support.

From the documentation, I understand that Railway provides Static Outbound IPv4 addresses on the Pro plan, mainly for outbound allowlisting/firewall use cases. I also noticed that Free plan users only see Private Networking and the Outbound IPv6 toggle, but not the Static IP option.

I would like confirmation on the following points:

1. Does Railway currently provide only Static Outbound IPv4 addresses and not Static Inbound/Public IPv4 addresses?

2. Are the provided outbound IPv4 addresses shared among customers or dedicated per service/project?

3. Does Railway support Static IPv6 addresses in any form (inbound or outbound)?

4. On the Free plan, is there any way to obtain stable/static outbound IPv4 addresses, or is upgrading to Pro mandatory?

5. If a service is redeployed or moved across regions, will the assigned outbound IPv4 addresses change?

6. Is there any roadmap or planned support for dedicated static inbound/public IPv4 or IPv6 addresses?

My use case involves IP allowlisting and understanding whether Railway networking is suitable for services requiring fixed public IP access.

Thanks.
