Thanks, Manuel.  Now I know what to do, and am more confused
than ever. (!)

What I find peculiar is that I didn't set up IPv6, and I'm
sitting behind a 1.42 firewall.  I'm not up to speed on IPv6, so
my network isn't either (no surprise).  

I take it that www.netbsd.org has an AAAA record, and that each
application has its own IPv4 fallback implementation.  Shouldn't
the app determine if indeed there is any IPv6 support locally
before attempting to reach a host?  "Falling back" on every name
resolution would be unnecessarily expensive. 

(Now that you've opened the Pandora's Box, I figure I might as
well try to learn something.)
