Public IP address

[Mad94]

Hello, 

I have  fritzbox6660 and I live in BW. How can I get a public IP address? 
I have an app to run and I should have public ip address ipv4 for this purpose, and currently I assume I only have a static ipv6 which is not suitable for my application. 

Thanks a lot!

Public IPv4 addresses are not part of customer contracts - and haven't been for nearly a decade now.

Either you use IPv6 -or- you need to switch to a much more costly business contract.
