Code review comment for lp:~julian-edwards/maas/network-gateway-ui

Two nitpicks about this bit you're adding in the factory:

        if default_gateway is None and random.choice((True, False)):
            default_gateway = unicode(IPAddress(network.first + 1))

The factory has a helper for random.choice((True, False)): pick_bool().

Why are you forcing the gateway to be network.first + 1? I'd use self.pick_ip_in_network(network).
