addressable !== routeable !== reachable.

IPv6 will certainly REDUCE the need for STUN, but there are still (many) cases where you don't want to be "reachable by default", in which case you need a stable reference for negotiating routing and reachability (e.g. STUN).

IPv6 could have and address for "reachable by default", I find that very useful, also IPv6 allow many addresses so that is not wasteful.

Yeah, but if it’s reachable by default then it’s (by definition) open to the world. Otherwise (if you mean routable by default) you will still end up temporarily punching holes in your firewall, which you will need to close afterwards, and possibly recycling your ip so you aren’t still routable on that last used address. sounds like you would personally end up being a STUN server!
