You're running 8.1.2.  Use "dig version.bind txt chaos" to see it.

www.netscape.com seems to be delegated to DNS servers that try to determine
which web server is closest to the client, and then give out an alias for
that server.  For some reason, it decided once that the server in Japan was
best for you.

This time it determined that the ones in Mountain View (I'm guessing that's
where www-mv is) are closer to you.

What's wrong with that?  Answers from cache are *supposed* to be
non-authoritative?

Sounds like a problem with the way their specialized DNS servers try to
determine which server to hand out to you.  It's not your problem, you're
just returning whatever they tell you.
