That’s exactly backwards. The intent is to provide aggregation along celestial body lines. The network operating environment is pretty spartan. Deep space communications are expensive, slow, and have major outages when physics precludes the connection. Redundancy is luxury for the distant future. There will be relay nodes in place, and eventually many different surface networks that will be interconnected. Those networks are deployed by a number of different space agencies, who are somewhat mutually cooperative, but need gudiance about network architecture. Now, according to current policies, each of these agencies will use part of their own address space allocations, presumably one prefix per network. As those allocations are from different RIRs and different blocks, all of those prefixes will result in explicit routes carried across interplanetary links. By doing allocation along celestial bodies, each agency will be able to get a prefix for their network from the common block for that specific body. These can then be aggregated when they hit interplanetary links, resulting in minimal overhead. Regards, Tony
