I know ARIN doesn't care about routability and all that, but good luck with those /28s.
I do wonder though what the purpose of this block is?
https://www.arin.net/policy/nrpm.html#four10 "4.10 Dedicated IPv4 block to facilitate IPv6 Deployment When ARIN receives its last /8 IPv4 allocation from IANA, a contiguous /10 IPv4 block will be set aside and dedicated to facilitate IPv6 deployment. Allocations and assignments from this block must be justified by immediate IPv6 deployment requirements. Examples of such needs include: IPv4 addresses for key dual stack DNS servers, and NAT-PT or NAT464 translators." This was set aside just in case the IPv4 market doesn't pan out and you can no longer get BGPable /24's. The presumption is that if we hit the kind of crunch this block is reserved for, convincing folks to route /28's will be the least of our problems. Regards, Bill Herrin -- William D.
