>Description:
dig reports a host's IPv6 address, even though the goes to the
IPv4 address. I cannot reach this host's IPv6 address as I do not have
a default route at the moment.

>How-To-Repeat:

redback# dig @munnari.oz.au com.au ns | grep FROM
;; FROM: redback to SERVER: munnari.oz.au  2001:388:c02:4000::1:21

redback# tcpdump host 128.250.1.21 and port 53
tcpdump: listening on le0
12:00:27.717489 redback.spyda.net.53380 > munnari.OZ.AU.domain:  4+ NS? com.au. (24)
12:00:27.769573 munnari.OZ.AU.domain > redback.spyda.net.53380:  4- 0/8/6 (325)
