Keith, It seems likely that cable mso's similar will dole out /64's to customers one at a time, ... The issue is that IPv6 is architected to give sufficient addresses to end users, and by screwing with this ARIN is harming both deployability of IPv6, manaegability of IPv6, and usability

end users are still long enough to allow a couple of additional layers of network to be hung off of them. The only way to do what you want is to effectively have a variable length address. While there were a few crazy advocates of this many years ago, they were shouted down. Tony Li Lead

Keith, perhaps, but one might also reasonably expect 2^0 networks to be insufficient. At the risk of repeating myself, I respectfully disagree. Given that you can reasonably build a flat subnet of 1000 hosts today, it does not seem like an unreasonable entry point. Mom Pop 6-pack have

variable length addresses are a better idea than it appears at first glance. they do bring certain difficulties with them, especially when trying to do fiber-speed switching in hardware. Poppycock. Hardware for switching variable length addresses first showed up about 15 YEARS ago. This

When they do, they are violating the premises on which they received their allocation. As such any ISP which is not willing to provide a /48* to an end-user should get their IPv6 allocation revoked by the RIR. Could you please site chapter and verse? Here's what I can find:
