At time of config render the charm currently attempts to get this information from the runtime configuration of the ``o-hm0`` interface.

As you have found and described this is racy as there is no guarantee that the interface has configured itself at that point in time.

Other options could be to load state from Neutron, or store a extra state in the charm with the address.
