[CESG] FW: [EXTERNAL] I-D Action: draft-li-tiptop-address-space-02.txt

Tue May 26 07:39:37 EDT 2026

In a bit of casual googling, I couldn’t find a requirement that a RIR or NRO be open to all comers.

Hi Daniel, all,

As you may recall, we have already discussed in the last couple of years the activity of the tiptop WG within IETF which is pushing for an IP-based solution for space communications, with the objective of re-using/profiling existing IETF protocols (e.g., IP and QUIC mostly) for their application in space. The full list of documents (I-Ds) prepared so far is available here: https://datatracker.ietf.org/group/tiptop/documents/

At the time the WG was still a non-WG, many of us were involved in debating the suitability of an IP-based approach also in light of the CCSDS orientation to go for DTN-based solutions, but eventually IETF agreed to make such a WG though with a specific scope (a bit narrower than that proposed in the original non-wg deepspace). As far as I know Marc Blanchet developed some tools to prove the feasibility of an IP-based approach for emulated Voyager-communications. Some info are available on the WG Github.

I think that what is a bit concerning is the view shared within this WG by some members with respect to CCSDS role for defining RIRs: “Observation: To achieve (3), CCSDS is disqualified as a potential RIR for Space, because CCSDS is closed club.  It is NOT open to all comers on an equal footing at present.”

Regards,

Tomaso

My own sense about extra-terrestrial networking goals/objectives is that:

1) We need aggregation to enable routing to scale.  It is the only approach known to work.

2) We need to have consistent allocation policies applicable to extra-terrestrial address allocations to achieve aggregation.

3) We want to avoid any national/nationalistic impairments to either of the above.

Observation: To achieve (3), CCSDS is disqualified as a potential RIR for Space, because CCSDS is closed club.  It is NOT open to all comers on an equal footing at present.

Now, I am not certain how best to achieve those 1/2/3 goals, but it seems worth having a broad discussion.

It might be worthwhile to focus initially on goals/objectives, perhaps with a focus on 1/2/3 above, which are technical questions.

Of course, ICANN, the ICANN NRO, and existing RIRs are part of the overall landscape  IETF’s role is on the technical substance, which I’ve tried to capture in 1/2/3 above.  Possibly I’ve missed other technical aspects of extra-terrestrial networking.

Yours,

Ran

Internet-Draft draft-li-tiptop-address-space-02.txt is now available. It is a
work item of the Taking IP To Other Planets (TIPTOP) WG of the IETF.

   Title:   IP Address Space for Outer Space
   Authors: Tony Li
            Marshall Eubanks
   Name:    draft-li-tiptop-address-space-02.txt
   Pages:   5
   Dates:   2026-05-20

Abstract:

   The exploration of outer space depends heavily upon communications
   technology and in many cases, uses IP.  IP address allocation has
   been formally assigned to Regional Internet Registries (RIRs), but
   there is no formal allocation of address space for networks in outer
   space.

   This document describes updates existing address allocation
   procedures to include address space for outer space.
