 ros2 node list

will show all the nodes running on my network, but how can I find out which nodes are running on which hosts, or where a particular node is running?

Application: For a TurtleBot 4 Lite running ROS2 Galactic, there are nodes running on the Create3 base, and more nodes running on the Raspberry Pi4 inside the accessory tray, and I have my desktop ROS2 environment running rviz and rqt-image-view. I would like to be able to determine what is running where.
