If you don't mind running IPv4 in a tunnel over that IPv6 network, you can do DSlite or 4rd <http://tools.ietf.org/html/rfc6333> <http://tools.ietf.org/html/draft-despres-intarea-4rd-01> < http://en.wikipedia.org/wiki/IPv6_transition_mechanisms#Dual-Stack_Lite_.28DS-Lite.29 > On Friday, September 21, 2012, Mark Radabaugh wrote: > > The part of IPv6 that I am unclear on and have not found much > documentation on is how to run IPv6 only to end users.
