[arin-ppml] IPv6 as justification for IPv4?

[Scott Leibrand]

Tim,

I think this is an issue that is only going to get worse as IPv4 exhaustion
makes upstream ISPs less willing to allocate large blocks of addresses to
downstream customers.  In such a situation, I think it is entirely
appropriate to allow a downstream ISP, which has a customer base large
enough to justify a /23 (and is allocating those customers ARIN-assigned
IPv6 space) to also get approved for an IPv4 /22, and be eligible to
acquire it on the transfer market if the ARIN free pool is exhausted.  I
would personally rather not liberalize 4.2.1.6. Immediate need, as that is
supposed to be for "exceptional" cases, but perhaps adding a clause to the
first bullet point of 4.2.2.2. Multihomed would be appropriate.  Maybe
something like "or demonstrate the assignment of IPv6 addresses to more
than 500 devices"?

Would that kind of policy help for a situation like yours?
