[arin-ppml] Addressing for other planets

[Daryll Swer]

If we create GUA aggregates per planet (like we did on Earth with
2000::/3), should we also create /10s per planet, excluding Earth? I'm
curious to hear what people think we should do for prefix length allocation
to large bodies (planets) and possibly moons as well.

I don't think we should use 2000::/3 for anything outside Earth's immediate
orbit, maybe the Moon at most. I think a *different* /3 from IANA should be
used for space networking. This would allow clean aggregation per large
body (planet or equivalent) and clean segmentations across RIRs (if we
decide RIRs have allocation authority for space networking).
