Static outbought IPs are only available on the Pro plan.

I am on the Pro plan

You are on the Hobby plan as per your badge.

How can I be on the Pro plan

By creating a team workspace - https://railway.app/new/team

But before you upgrade, what is your use case for the IP.

I am internet provider, I use mikrotik server, so I need IP address in to allow to this IP to contact with mikrotik server

Gotcha, then the Pro plan is what you want, once on the Pro plan you can go into the service settings to get the IP.

IP address on my hobby plan is dynamic?

On my winbox server I got IP address from my app on railway. So I put IP address on my winbox, I got correct connection. I am a afraid that IP would changed

Yes it's dynamic and could change between deployments.

Your usecase is not Hobby related, you would need to be on Pro regardless.

Okay, thank you

Hello, I upgrade to pro plan, how can I get IP address, I search everywhere I did not find it

That would be in the service settings.

Enable static IPs ?

Correct.

Okay, thank you
