By definition, every single one of them that buys wireless router, then buys another and hangs it off the first. That happens more often then you would think.
A /62 takes care of that unusual case, no real need for a /56 for the average residential user; that's just excessive. Before wondering about the capabilities of home routers.. one might wonder if there will even be _home_ "routers" ? The consumer-level boxes for home users that do NAT for V4, for V6 may well act more like Layer 3 bridges, and (once need for IPv4 support goes away) be simple Layer 2 bridges that can be small lower-powered, fairly dumb devices that just act as pass-through for the ISP router with a basic transparent firewall. And only route/NAT for IPv4. There are reasons to doubt that PD will be supported on consumer level devices; or to expect devices may have only limited support for PD. The availability of an entire /64 means users' 'internet sharing boxes' no longer benefit from NAT or routing capabilities; the user has all the IPs they need from the ISP, and doesn't _need_ to create their own subnets. NAT'ing/routing in IPv6 becomes more of a feature only Service providers and large entities really need. -- -J
