The nameserver is asking for address records. Updating
your packet sniffer so that it knows about current records
will help.

AAAA was defined in 1995, A6 was defined in 2000 to be its
replacement however A6 moved to experimental in 2002 and
we moved back to AAAA.

From the look of the trace you are running BIND 9.2 or earlier.
BIND 9.3 onwards don't look for A6 unless a client asks for A6.
