[arin-ppml] Addressing for other planets

[Alejandro Acosta]

For me, it makes a lot of sense. However, I’d add one more layer: I 
would suggest a separate `/3` subnet just for planets (unfortunately 
other planets than earth) and another `/3` for other objects (like 
asteroids or Pluto, which isn’t actually a planet). Addresses for 
natural satellites would fall within the address space of their 
respective planets.”

Alejandro,
