Describe your changes
JupyterHub controls which interface(s) the singleuser server listens on.
The IP is set in the Spawner configuration, and passed to the singleuser server in the environment variable
JUPYTERHUB_SERVICE_URL
:https://jupyterhub.readthedocs.io/en/latest/reference/spawners.html#note-on-ips-and-ports
Docker-stacks shouldn't override it. For example, if you configure a JupyterHub container spawner to use a docker-stacks image and use the default CMD it won't work with IPv6.
