Comment 3 for bug 1568809

The requested feature is available in neutron APi from long ago. You can use all things through CLI for neutron (neutron CLI or openstack CLI).

The reporter seems to request a network related feature to horizon. Horizon is a GUI project, so as horizon we only handle GUI side. As Horizon, we can add a menu like "Add IP" or "Remove IP" to the port table (but it is a minor feature and can be low-hanging-fruit)
