Daryll - Modeling requires engineering to specific assumptions - did you gain any perspective into number of network operators per planetary body and number of planetary bodies they are envisioning? Is there any insight into what common registry services (whois/RDAP, reverse DNS, IRR, RPKI) they expect to operate across these prefixes? Is it possible that any of them could join the discussion here or on the corresponding RIPE mailing list?

Has anyone looked at /48's growth lately? Yeah, not pleasant. I do not want that in that space. It's unclear which real-life space network operator(s) are treating this as a joke or prank; perhaps Fernando Frediani has industry insights that we are unaware of. I, for one, am not known for having a sense of humour in a professional setting. Work is work, engineering is engineering, and we must evaluate and assess data, facts, figures and peer reviews. -- Best Regards Daryll Swer Website: daryllswer.com<https://l.shortlink.es/l/5c534d492ecd030217c5e35e643b3493eb6e10a8?u=2153471> On Fri, 20 Feb 2026 at 22:11, Tony Li <[email protected]<mailto:[email protected]>> wrote: Hi Fernando, > That's my point.

We end up with a swamp in space, with grossly inefficient routing, no aggregation, coupled with low bandwidth, long latencies, anemic processors, and insufficient memory. I would like to avoid that.
