Yes, and if you have a well-designed network that has IPv4 follow the
same packet path as IPv6, OSX will happily flip-flop back and forth 
between IPv4 and IPv6 between http request to the same server.

Not overly deterministic, and not helpful when looking for "sometimes
it does not work" errors (like, an Apache ACL mistakenly permitting only
one of the protocols).
