Yes, there will be a market for a few IPv4 experts for some time to come,
just as centuries after the height of its demand there is still a market for
hand-made masquerade masks in Venice. My point was that the market will not
sustain the number of IPv4 experts that it does today, just as there are
only 2 mask makers left in Venice.
Assuming the IPv4 space is fully allocated/assigned by 2010, by 2015 the
number of people that can make a living by only knowing IPv4 will be
substantially lower than where we are today. By giving preference to IPv6
when it works, by 2015 the amount of IPv4 traffic will be effectively zero
from the perspective of today's giddy heights. Yes, IPv4 will persist for
decades within organizations (HP printers with embedded IPv4-only
controllers will not die), but those islands will be parked in cookie-cutter
corners of the network where no expertise is required.
