> NAT comes up a lot and that is a major change. Erm ... you are aware that NAT is not a function of IPv4, right? That IPv4 worked completely without NAT for the first one and a half decades or so? That NAT was invented later as a workaround for the lack of addresses? IPv6 works exactly like IPv4 in this regard, it's just that you have enough addresses, so you obviously don't continue the workaround for a problem that you don't have anymore, but operate IPv6 networks exactly the same way you would operate IPv4 networks if it weren't for the lack of adresses.
