Comment 7 for bug 1557769

@Stuart,
I think that the only provider that exhibited this behavior was MAAS. Because there were considerable differences between MAAS 1.9 and 2.0, I am guessing that you are not seeing this behavior with Juju 2.0 is because you are running against MAAS 2.0.
Could you please clarify which provider, including versions, was causing you issues?

I suspect that the docs and Juju are correct in saying that we expected an IP to be returned as private-address value. So there may not be anything to do here.
