Below is what the answer should look like.  The TTLs should be these
values shown below (6 days and 1000 hours) and "aa" should be set
in the flags and "ra" should NOT be set in the flags.  You have a
"transparent" DNS caching proxy between you and the Internet as a
whole.

Some routers try to be "helpful" by maintaining a DNS cache.  You
need to turn the "feature" off.  Otherwise it is your ISP doing it
and you need to get them to stop mucking with your DNS queries.

Named issues non-recursive queries and sticking a normal recursive
server in the path that pays attention to the setting of "rd" doesn't
result in getting the required answers back.
