For those interested in reading or reviewing the ensuing discussion, here is a URL. http://marc.theaimsgroup.com/?l=ipng&m=106614091529296&w=2 Admittedly I can't remember where I read it, but I've come across a suggestion that enterprise networks adopting IPv6 is likely to happen before ISPs provide it in any big way, as enterprise networks have more to gain from the technology (well, possibly, assuming they can be convinced that "proper" address space is better than NAT). Once enterprises have it, they will then ask for it from their ISP. I'd agree that expecting the drive for it to come from ISPs is probably incorrect. Maybe the focus needs to be to work on IPv6 protocols that enterprises need. Anybody want to work on NetBIOS over IPv6 ? After all, File and Print would have to be the "killer" application for enterprise networks - it's the application that got networks into most enterprises in the first place in the last 10 years.
