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!
