Welcome to the dark side! Unfortunately, that is how many people think of IPv6 at the moment. While IPv6 is by no means a new thing, in my experience it is still something that almost no one has deployed in their own networks. While working with hundreds of different companies all over the world over the past few years, I have come across only one organization that was running IPv6 over their entire production network, and it wasn't even true native IPv6. Instead, they were using a tunneling technology, called ISATAP, over their whole network in order to make all of the servers and clients talk to each other using IPv6 packets, but these packets were still traversing an IPv4 physical network. Don't get me wrong; I have found plenty of cases where companies are toying around with IPv6 and have some semblance of it configured on a sectioned-off piece...
