(many excellent reasons removed) Let me just add on: +Bonus Fear: Because IPv6 deployments are small and vendors are still ironing out software, there's concern that deploying it in a production network could cause issues. (Whether or not this fear is legitimate with vendor x, y, or z isn't the issue. The fear exists.) +Bonus Uncertainty: There is a lack of consensus on how IPv6 is to be deployed. For example, look at the ongoing debates on point to point network sizes and the /64 network boundary in general. There's also no tangible benefit to deploying IPv6 right now, and the tangible danger that your v6 deployment will just have to be redone because there's some flaw in the current v6 protocol or best practices that will be uncovered. +Bonus Doubt: Because we've been told that "IPv4 will be dead in 2 years" for the last 20 years, and that "IPv6 will be deployed and a way of life in 2 years" for the past 10, nobody really believes it anymore. There's been an ongoing chant of "wolf" for so long, many people won't believe it until things are much, much worse. -Dave
