Do you get the same effect if you ping an IP number directly? eg.
instead of

  ping6 www.freebsd.org

try:

  ping6 2610:1c1:1:606c::50:15


If there is a difference, that suggests the problem is not actually with
the pinging, but with the DNS lookup to find the AAAA record of the host
you want to ping.

	Cheers,

	Matthew
