So I am curious, and probably out of touch.

MAC addresses are supposed to be unique hardware device addresses  that ultimately come from a registry administered by IEEE and are supposed to be allocated exactly once to one hardware entity.

Is MAC address randomisation something that IEEE approve of, in which case how does the registry work, or are we at risk of working on a problem that results in an interSDO dispute?
