In any case, content providers can avoid the confusion if they simply put up a local 6to4 router alongside their 2001:: prefix, and populate DNS with both. Longest match will cause 2001:: connected systems to chose that dst , while 6to4 connected systems will chose 2002:: as the dst. There is no ne ed Huh? Longest match done by web browsers and other applications? Since when? FreeBSD 6 has is as part of the standard getaddrinfo() implementation.
I don't see that do any differentiation between 2001::/32, 2002::/16 and 2000::/8; only between IPv6-mapped IPv4 addresses and various interface/link/site-local addresses. And even that function has a big * XXX: we should standardize the functions and link them as standard * library. warning stuck on top of it
2002::/16 vs non 2002::/16 should be in the policy table. This is the default prefer ipv6 policy table for FreeBSD 6.4-PRERELEASE. There is also a alternate prefer ipv4 policy table that will be set if IPv6 is disabled.
