n our last article[0]
, we wrote about the onset of scarcity and
the problems that are likely to ensue as a result. We character-
ized the problem we face as the gap, the length of time between
the end of IPv4 plenty and the beginning of a universally reachable
IPv6 Internet. Noting that any solution should either make the gap
shorter, by bringing forward full IPv6 deployment, or make it less
painful, by reducing the pressure of IPv4 scarcity, we propose that the
fairest, most neutral way to encourage networks out of IPv4 while
providing help for those who need it is to introduce a market-based
IP address trading exchange. Let us explore now how such a system
could work.
