Naive, as I am, I am still a little unsure of how much the distribution of ip addresses is ICANN's business.
It is ICANN's business to the extent that ICANN runs IANA which handed out most of the original /8 allocations, and has a modest pool of returned space. But IP space routing happens from the bottom up, unlike domain names which work from the top down. If the RIRs decided they didn't like IANA's policies, they could ignore IANA, allocate space to their existing and new customers any way they want, and there wouldn't be anything ICANN could do about it. So even if we were to dislike the RIRs' plans, I wouldn't waste our limited volunteer time on it. As several of us said before, if this is something of importance to you, engage directly with your local RIR. R's, John
