I think that when they sat down and tried to figure out a neat way to do this they quickly realised that legacy support=more code=more bugs=more exploits and less reliability.

IPv6 was a chance to re-imagine the internet all over again. (And lets face it, the internet is still in it infancy, we don't even have a full set of working browsers yes. Tongue

), and they have done everything they can to make sure these problems don't come up again.

No, the answer given by jib was completely correct, it is completely impossible (not merely "hard" or "too much work") to build such a protocol.

Nah, I dont think its hard to imagine a cross compatible protocol with IPv4, it just would have needed to be implemented top-down, assigning "IPvX" a huge subnet of availabe IPv4 addresses, with ISP's providing transparent bridging. Eventually enough Devices would be in the new subnet and the Ipv4 bridging can be cut and the rest of the new address space opened up.

Anyway the moment is past, IPv6 is what we got, so any type of seemless migration is impossible.
