Ouch. I don't know what the intended purpose of this article is, but it is misleading and just plain wrong on a number of points. Most of us in the IT profession know about IPv6. The "reluctance" to implement it is not on our part, but on the part of non-IT budget approvers who don't want to spend the money to upgrade current infrastructure (i.e. routers & firewalls) until they absolutely have to. IPv6 will only be adopted widespread when businesses can't do their business any more with IPv4.
