I'm not sure how a network with a router can handle multiple IPv6 addresses, one for each device attached to an intranet.
An IPv6 router will be assigned a specific range of of addresses called a /64 or /56 or however long your ISP decides.
Take a look here at the Linksys screenshot - perfect example:
»
[IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEPD)You will be assigned a block of addresses, for example:
2601:c:x:x;x:x:x
Your router will then give all your other devices an address say:
2601:c:5601:AF:23:11:11
2601:c:5601:2B:43:1c:1F
2601:c:5601:23bf:a30c:f33e
Or whatever - Those aren't exact IP addresses but you get the idea. Your router will also have the IPv6 Firewall which will block scans/pokes and whatever else coming to your addresses unsolicited.
This is why it's inportant to have a good firewall for IPv6 and not just enable tunnels back to your network. Surely you can connect to IPv6 networks but without the support of router or software firewall they can connect just as easily back to your system.
