Hi, Bill and Paul.

Not only is it counterproductive to interest in migrating to IPv6, but it encourages an unbalanced competitive field. For instance, an ISP with access to IPv4 addresses in the ARIN region will have an upper-hand competing in Asia (during this period of transition), unless ARIN makes resources available more broadly. On one hand, this sounds good - since I live in North America. But on the other hand, all things considered, I think this is a bad situation.

I'd like to add to this, by noting that there are many shades of "shortage" - and that we can discuss these in terms of cost. In recent history, an IPv4 address has been inexpensive (RIR fees are relatively small on a per-address basis). And in the near future, during a state of true and complete "exhaustion", the cost of an address will be relatively high (based on the business value enabled by the address). Between now and then, in a market-driven address allocation environment, the prices will probably rise. This will act as an encouragement for IPv6 transition, without the ugly scenario of "hitting a wall" or "driving off a cliff".
Of course, because the effectiveness of IPv6 requires that we all transition together, it would be undesirable for one region to "hit a wall" while another continues with artificially low prices based on RIR rationing. I think Paul is wise for pointing this out.
