queries for external hostnames inside my domain?

You might want to look at the requestor machine's "search" domains.

If the stub resolver starts appending search domains when it doesn't get a response it can use.

    Good point -- even as I asked that I had something like that scratching
    on the inside of my head that I didn't quite remember or get.  That
    makes sense.

    I know the other comes from inside my dom as well, but why the
    ipv6 queries generate both an absolute query (from dns-root), and a
    relative query inside my domain?  When I look at it, I can tell
    it looks odd and something seems to be looking up external domains from
    the internal interface, but what might be causing it to also look for
    it in the internal domain?  A program bug?

    Thanks!
