Re: IPv6 will never fly: ARIN continues to kill it

Michael,

Here's a decision table for you:

1. Do you need addresses that are routable from the global
    Internet, from anywhere?

    (Its not clear to me that you do, because you only need to
    do that within your own network and a couple of well
    known external sites perhaps.)

    a. If not, maybe you should look at ULAs. RFC 4193 allows
        you to get these addresses randomly, and you do not
        need to ask permission from anyone to do it. You could
        have your addresses today if you wanted to.

    b. Proposals have been floated about non-random ULAs
        as well. Right now we do not have one, but I'm not
        sure you need this for your particular case.

2. If you do need addresses that are routable, is it
    sufficient for you to work with provider-aggregated
    addresses that you get from your ISP (not from ARIN)?

    If yes, get the addresses and use them!

3. If you do need addresses that are routable AND
    you have multiple ISP connections and want to stay
    away from an address renumbering if you need
    to change ISPs, then you need PI. You are starting
    to get PI space, but as numerous PI items in the
    global routing table cause pain for routers, this
    will likely be available only for larger enterprises.

    There is ongoing work to try to design a better
    routing system that would be capable of keeping
    tens of millions of prefixes or more, in the IRTF.
    If and when that work succeeds, it would be possible
    to allocate everyone their own PI prefix. We are
    not there yet.

In any case, FWIW, I think it would make sense for RIR
address allocation rules to allow IPv6-only operations
and not just those that need both IPv4 and IPv6 address
space.

Jari
