I meant real-world application.

Orbits are limited due to the required combination of speed and altitude. There are a limited number of
achievable altitudes and collision avoidance also creates interesting problems in time-slotting for
orbits which are not geostationary.

Geostationary orbits are currently limited to one object per degree of earth surface, and even at 4x
that, you could give every satellite a /48 and still not burn through a /32.
