Hi Paul,

I'm an ARIN facilitator.
Can I run an auction today on eBay for address space?
If eBay requires a letter of approval from ARIN, will that be provided?

As to your issue about what happens after IPv4 is at its best and highest 
use, I have given this some thought over the years.
Have you considered that a robust trading market and CGN might buy us enough 
time to come up with some kind of backward compatible successor protocol to 
Proposals for these kind of solutions have been made in IETF but are 
routinely ignored.
To my mind there is room in the IPv4 header to expand the effective address 
GGN does this effectively and largely transparently today using the 
additional room in the  port number part of the header.
Every TCP connection uses IP+port, and we have 65,000 ports per IPv4 

The dual-stack transition is a failure, it is time to recognize that the 
lack of an economic motive for IPv6 created a situation where dual-stack was 
John Curran was right back in 1994, it's time to recognize that now: 

And we have gotten pretty darn good at traversing NAT already, despite the 

It does not further your position to openly wonder whether those who 
"complain" are "hoarders and speculators".
