eventually this few lines show why this thread goes so far ... 

your computer will or better CAN use ipv6 when it is on a ipv6 network and 
nothing else, ipv6 WILL NOT come eventually available on your ipv4 network 
(unless it's address space change ...)

this has nothing to do with vista or dawn, this is a routing issue and as long 
as you are NOT on a ipv6 network you do NOT need ipv6 on our machine, still 
beeing able to access ipv6 networks ... as weel as ipv6 networls can access 
ipv4 networlks guys, if not so all this ipv[4|6] stuff wouldn't make any 
sense ...

as long as you talk in endpoints you also can access any rfc1918 address as 
long as you have some setup (VPN?) for that, so what you say here is not 
exactly true, either for windows nor for unix, the OS at the end has 
absolutelty NOTHING to do with ipv6 neither with ipv4 ...

so final point here is that you need ipv6 on your machine when you are on a 
ipv6 network or want by any means connect directly to a remote ipv6 endpoint, 
similare as you do a VPN connection to a rfc1918 network wether this are 
tunnels or whatever provided by either satans or daemons ...

guys please ...
