I think the a reserved /11 policy for all and from the IANA frags and
eleasing this back to the free pool would provide for the same

Delete it and return it to the pool.

I was looking at Geoff Huston's graphs (http://www.potaroo.net/tools/ipv4/) and noticed that both RIPE and APNIC, by coincidence, will be using up the first /10 out of their reserved /8s at about the same time, near the end of this year. A naive calculation says that APNIC will go through the /10 in about 3.5 years, and RIPE in about 2.2 years. Of course it is difficult to predict how the runout of the reserved /10 under 4.10 will look, but I think it's reasonable to assume that it won't be any slower than 2-3 years, since unlike RIPE and APNIC there's no limit to how much space an entity can receive under 4.10, only the pace at which it can be handed out; assuming the maximum rate, a /22 can be issued to someone every two years, r
