you can control this using the IPV6_V6ONLY socket option, like so:
s.setsockopt(socket.IPPROTO_IPV6, socket.IPV6_V6ONLY, 0)
unfortunately python 2.3.3 doesn't yet make that constant available
though it is fixed in cvs. you could glean the value from the headers.
the default setting has been in flux on various platforms recently,
all the more reason to want to always set it explicitly...
