Thanks for this feedback.  It is a sentiment I've heard from others, over the past year or two.  And it deserves some credit for emphasizing and promoting IPv6.

However, I disagree; I think such a view ignores the present reality, in which IPv4 is the dominant network protocol.  I would be shocked to learn of anybody, who is responsible for a production Internet-connected network, that is willing to return all of their IPv4 addresses and rely completely on IPv6 at this time.  I hope we get to that point in the near future.  But between now and then, we have a need for both protocols.

Given that the need currently exists, and given that the RIR supply is almost exhausted, it is my opinion that we should implement policies to more effectively manage IPv4 numbers during the transition period.  If we don't, then new networks may find it impossible to acquire needed IPv4 resources, while existing networks hold idle resources with no incentive to share them.  Further, the gap between those with excess supply and those with unfulfilled need is ripe for exploitation, and change is happening whether we prepare for it or not.

In other words, IPv6 transition will happen for its own reasons; we don't need to further break IPv4 in order to encourage it.
