Users may also want to subnet their own network. So they need at least something like a /60.
This is not a "maybe", Mr. Gilmore. It's repeating the same mistakes of IPv4.
Mr. van B, your comments would be laughable if they weren't so absurdly horrific. I've lived quite productively behind a single IPv4 address for nearly 15 years. I've run 1000 user networks that only used one IPv4 address for all of them. I have 2 private /24's using a single public IPv4 address right now -- as they have been for 6+ years. Yet, in the new order, you're telling me I need 18 billion, billion addresses to cover 2 laptops, a Wii, 3 tivos, a router, and an access point? Did we suddenly jump 20 years into the past? This is the exact same bull**** as the /8 allocations in the early days of IPv4. The idea of the "connected home" is still nowhere near *that* connected; no matter how many toys you have in your bathroom, it doesn't need a /96 of it's own. (which is an entire IPv4 of it's own.)
Why do people avoid and resist IPv6... because it was designed with blind ignorance of the history of IPv4's mistakes (and how we *all* run our IPv4 networks.) Dooming us to repeating ALL those mistakes again. Exhibit A: With IPv6 Address Autoconfiguration (tm) (patent pending), you don't need DHCP. *face plant* The IPv4 mistake you've NOT learned from here is "rarp". DCHP does far more than tell a host was address it should use. (yes, I've called for the IPng WG member's execution, reanimation, and re-execution, several times.)
