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.”

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).

Hi,
As part of the IETF TIPTOP working group, we are working towards
enabling the Internet in outer space. We would like to direct
your attention to a couple of recent Internet drafts that may be
of interest:

The latter has direct implications for the ARIN community,
I would welcome any and all comments.
