[arin-ppml] Addressing for other planets

[John Curran]

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?

Thanks,
/John

I looked into some people that I know who currently operate real-life space networks:
The sentiment I'm getting is: This is serious; it's not a joke, and we/they want IPv6 for space to be properly subnet modelled, with no IPv4 psychosis or, what I personally dislike even more, /48 psychosis in the DFZ table. 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.

Hi Fernando,

> That's my point. What is the issue of they using the already owned prefixes they got from their respective RIR and if necessary request more ?

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.

Tony
