Waste will kill ipv6 too

Wed Dec 20 19:31:13 UTC 2017

This may be useful as well, somehow related, as using /64 has a clear advantage:

        Every time I see these "Look how many more addresses we have now with
        IPv6", I just shake my head.

          Yes, the address space is very large. But, all of the protocols, all
        of the addressing guides, all of the operational 'best practices', ALL
        OF IT, increases by orders of magnitude the amount of waste along with
        it. Call this the 'shavings', in IPv4 for example, when you assign a P2P
        link with a /30, you are using 2 and wasting 2 addresses. But in IPv6,
        due to ping-pong and just so many technical manuals and other advices,
        you are told to "just use a /64' for your point to points. So, the
        actual waste is dilutes the actual implementable size of the total ipv6
        address space due to the waste component. And I have not yet seen any
        study or even proposed theory to explore what the IPv6 Internet would
        look like, if used in place of all IPv4 in all the places and ways that
        it's used. I think, in time, we will discover that we have only
        increased our usable ip space by no more than 2 orders of magnitude over
        that which is achieved in ipv4, and we will be looking again at a global
        ip protocol upgrade I bet within my lifetime. While we are at it, why is
        nobody thinking or talking about the looming exhaustion of ieee OUI
        addresses? Network cards made 15 years ago and since consigned to the
        electronics scrap heap in the sky, take with them their addresses never
        to be reused again (unless you are a freak like me and keep some for
        'positively never assigned anywhere'). And old dead companies that were
        assigned OUIs, they get 24 bits of address space to take to their
        graves. We should be re-thinking mac addressing altogether too.

        (Please no hate mail, these opinions are strictly mine...)
