In a local network there is no point in using ipv6.
It is interesting when you run out of ip addresses for the amount of devices you have.
So in the open Internet.
Unless I am missing something.
A couple of things that IPv6 does better for local networks is link local addressing (fe80::). and multicasting.
In IPv4, they kind of hacked something out of 169.254, but if you have more than one NIC, it pretty much becomes useless.
If you have a service designed explicitly never to be accessed over a router, then you can live in fe80:: a lot more easily than trying to do the same thing with 169.254.
Why not? It's as easy as ipv4
If this was true then we would have swapped over by now.
Most people still see NAT as a security system.
