Tue 03 Jul 2012 08:37:57 PM UTC, original submission:  

TCP sockets bound to IP6ADDR_ANY allow listening for incoming connections on either IPv6 or IPv4.

UDP sockets require two PCBs to listen on both IP versions.

UDP is trickier than TCP because, once established, the PCB is set to v4 or v6 and all in/out packets share the same version. UDP would require some additional handling of default PCB version and current packet version.
