Hi, Pascal:

1)    " ... for the next version. ... ":    I am not sure that I can wait for so long, because I am asking for the basics. The reason that I asked for an IP packet header example of your proposal is to visualize what do you mean by the model of "realms and shafts in a multi-level building". The presentation in the draft  sounds okay, because the floors are physically isolated from one another. And, even the building is isolated from other buildings. This is pretty much how PBX numbering plan worked.

2)    When you extend each floor to use the whole IPv4 address pool, however, you are essential talking about covering the entire surface of the earth. Then, there is no isolated buildings with isolated floors to deploy your model anymore. There is only one spherical layer of physical earth surface for you to use as a realm, which is the current IPv4 deployment. How could you still have multiple full IPv4 address sets deployed, yet not seeing their identical twins, triplets, etc.? Are you proposing multiple spherical layers of "realms", one on top of the other?

2)    When I cited the DotConnectAfrica graphic logo as a visual model for the EzIP deployment over current IPv4, I was pretty specific that each RAN was tethered from the current Internet core via one IPv4 address. We were very careful about isolating the netblocks in terms of which one does what. In other words, even though the collection of RANs form a parallel cyberspace to the Internet, you may look at each RAN as an isolated balloon for others. So that each RAN can use up the entire 240/4 netblock.

Please clarify your configuration.

Thanks,

Makes sense, Abe, for the next version.

Note that the intention is NOT any to ANY. A native IPv6 IoT device can only talk to another IPv6 device, where that other device may use a YATT address or any other IPv6 address.

But it cannot talk to a YADA node. That’s what I mean by baby steps for those who want to.

Keep safe;

Hi, Pascal:

What I would appreciate is an IP packet header design/definition layout, word-by-word, ideally in bit-map style, of an explicit presentation of all IP addresses involved from one IoT in one realm to that in the second realm. This will provide a clearer picture of how the real world implementation may look like.

Thanks,

    As I understand: “IPv4 Realms” between “Shaft” should be capable
    to have a plain IPv4 header (or else why all of these).

    Then Gateway in the Shaft should change headers (from IPv4 to IPv6).

    Who should implement this gateway and why? He should be formally
    appointed to such an exercise, right?

    Map this 2 level hierarchy to the real world – you may fail with
    this.

    Hello Eduard:

    Did you just demonstrate that POPs cannot exist? Or that there
    cannot be a Default Free Zone?

    I agree with your real world issue that some things will have to
    be planned between stake holders, and that it will not be easy.

    But you know what the French say about “impossible”.

    Or to paraphrase Sir Arthur, now that we have eliminated all the
    impossible transition scenarios, whatever remains…

    There will be YADA prefixes just like there are root DNS. To be
    managed by different players as you point out. And all routable
    within the same shaft.

    Keep safe;

    Pascal

    Hi Pascal,

    In general, your idea to create a hierarchy is good.

    In practice, it would fail because you have created a virtual
    hierarchy that does not map to any administrative border. Who
    should implement gateways for the “Shaft”? Why?

    If you would appoint Carrier as the Shaft responsible then it is
    not enough bits for Shaft.

    If you would appoint Governments as the Shaft responsible then
    would be a so big scandal that you would regret the proposal.

    Hence, I do not see proper mapping for the hierarchy to make YADA
    successful.

    For the sake of it, Justin, I just published
    https://datatracker.ietf.org/doc/draft-thubert-v6ops-yada-yatt/.

    The first section of the draft (YADA) extends IPv4 range in an
    IPv4-only world. For some people that might be enough and I’m
    totally fine with that.

    Keep safe;

    Abe:

    To your first point about denying that anyone is being stopped
    from working on IPv4, I'm referring to users being able to
    communicate via IPv4.  I have seen no evidence of that.

    I'm not familiar with the process of submitting ideas to IETF, so
    I'll leave that for others who are more knowledgeable on that to
    speak up if they're so inclined.

    Thank you
