Re: Those brilliant minds who gave us IPv6

Well actually, they thought about coexistence since before the design was even chosen: RFC1671. IPv4 and IPv6 coexist perfectly. The underlying problem is that IPv4 (designed in the late 1970's) didn't provide any features to assist a version upgrade, except by including a version number. That makes interworking between IPv4 and IPv6 fundamentally hard. All that an IPv4-only device can do is barf when it receives an IPv6 packet. Please address all complaints to Bob Kahn and Vint Cerf.
