I still haven't seen any good argument for why residential users need /48s. No, I don't think "that makes all the address assignments the same size" is a particularly relevant or convincing argument.
We're doing /56 for residential users, and have no plans to change this.
If we were to give a /48 to every human on the face of the planet, we would use about .000025 of the total available IPv6 address space.
You are to be commended for your leadership in conserving space. Our children will surely be grateful that thanks to your efforts they have 99.99999% of IPv6 space left to work with rather than the paltry 99.9975% that might have been their inheritance were it not for your efforts. Bravo!
It makes a bigger difference if everyone starts using 6RD - to give out a /48 effectively requires a /16, and the number of /16s is by no means approximately infinite.
That is why the AC chose to allow for a /56 per end-site in the transitional technology policy (6rd is a transitional technology) and why we call for them to be issued from a distinct prefix separate from native IPv6 deployments. In this way, 6rd can be deployed sooner rather than later, but, we have the ability to move forward to a cleaner native IPv6 deployment and deprecate 6rd when it is no longer needed. Owen
