  There's a hackish solution that somewhat works -

    import socket
    s = socket.socket()
    s.connect(('', arbitraryPort))
    dottedQuad = s.getsockname()[0]

  I recommend using something like your ISPs news or email server for the
arbitrary host and port, since these will usually be fast to connect to.
