Comment 4 for bug 1736050

Is this a case of "without setting a specific binding, we end up selecting an arbitrary IP that you feel is incorrect"?
I suppose it could be "when guessing what IP to use, prefer the IP associated with the default gateway".
I think its still guessing, rather than doing something the user explicitly requested. It could be a more educated guess, but I'd like to make sure we have a way for the user to be specific before we do lots of work on heuristics that will always be wrong some of the time.
