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.

Prefix                          Prec Label      Use
::1/128                           50     0        0
::/0                              40     1     4997
2002::/16                         30     2        0
::/96                             20     3        0
::ffff:0.0.0.0/96                 10     4        0

I believe that is used for local address selection, not for sorting DNS 
replies.

        It's used for both.
