Mark,

You offer an accurate but incomplete assessment. IPv4 allocation's
upcoming transition to a zero-sum game might not push it above the
"cost" of IPv6. The economics in play haven't ruled out the
possibility. Should that occur, IPv6 will tend to fade to the
background during the following table-size driven router upgrade
cycle.

Bill Herrin
