If the app is written for IPv4 only, it must be modified in order to communicate via IPv6.  Some apps have been coded for dual-stack IPv4/IPv6, so they'll run either protocol version.  Ssh comes immediately to mind.

The API is the same (TCP/IP), but the semantics differ between IPv4 and IPv6 network programming.
