I have a rather theoretical question. While having a look a rqt_graph I wondered if there is a way to see which nodes are running on the same machine.

ros2 node info <nodename>

does not seem to offer this information.

Is this information available on the ROS2 Application Level or only on some other level?

I don't think there is currently a way to query the hosts of nodes remotely. I believe this information is available from DDS, so in theory a ROS API could be added to support such a feature.
