Time has not been kind to this article. It's basically a compete list of fallacies that people believe about ipv6.

Oh, is IPv6 now backwards compatible with IPv4? No? I guess not a complete list of fallacies.

Yes, v6 is backwards compatible with v4 now, via dual stack, Teredo, 6to4, 6rd, 6over4, ISATAP, 6in4/4in6, NAT64/DNS64, 464xlat, DS-lite, MAP-T/E, 4rd, LW4over6 and probably other methods I'm forgetting. In fact many of these were in there from the start, so it was always backwards compatible.

You could make a reasonable argument that it has too many ways of being backwards compatible, even.
