[address-policy-wg] "too many" /64 or /48 assignments causing address space exhaustion

Hi,

I support the concerns of Florian.

We need addresses for addressing AND ROUTING. In the original design a few
bits had been reserved for routing purposes in the IPv6 address scheme just
to facilitate routing in the future. These bits completely disappeared --
which is not a a problem in the first phase of the transition, where we are
now; however the missing functinality will case problems as the Internet
will further grow.

Jim, probably you are better expert in this field than me - what do you
foresee about scaling of routing and the possibilities of chosing between
different backbone service providers in the future?

Best,

Géza
