That's a good one.

<p>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.”</p>

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