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

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.

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
