For IPv4, there are prefix filtering guidelines, and the RIR assignments are compatible with them. Otherwise, you'd end up with PI space (or even provider allocations) which are not globally reachable to a significant degree. So the two concepts are not entirely separated -- and one stated goal for IPv6 is to mesh them together ("better aggregation"). > RIPE and all the other RIR's assign/allocate _Address Space_ to their > clients based on their need.

I wonder how one would get along with a /23 PI in 62/8. 8-> > But that is nearly impossible fortunately unless some big ISP's put > their hands together and force all you little folks out of the > routing tables. See, in the IPv6 world as envisioned by you (and others, of course), these little folks are called "waste" -- see <439442BE.2010509 at unfix.org>.
