[arin-ppml] Draft Policy ARIN-2017-5: Equalization of Assignment Registration requirements between IPv4 and IPv6

[Hadenfeldt, Andrew C]

Oppose as written, +1 on the points below (leave /29 alone, and would prefer to see /56 rather than /60)

Policy statement:

Amend 4.2.3.7.1 of the policy manual to strike "/29 or more" and change to "more than a /28".

Hello,
In my opinion...

Leave /29 alone or change it to "more than a single IP address." In these days of IPv4 shortage, substantial networks sit behind small blocks of public addresses. These networks should be documented with reachable POCs lest the anti-spam/virus/malware folks slam down /24 filters for lack of information about how misbehaving networks are partitioned.

Amend 6.5.5.1 of the policy manual to strike "/64 or more" and change to "more than a /60".

Change this to "more than a /56." Service providers should NOT be assigning /64's to end users. If you're doing that, you're doing it wrong. An IPv6 customer should be able to have more than one /64 subnet without resorting to NAT so /60 should be the absolute minimum end-user assignment, equivalent for all intents and purposes to an IPv4 /32. If we then want "equivalence" to the /29 policy so that individuals with the minimum and near-minimum assignment do not need to be SWIPed, it makes sense to move the next subnetting level up. In IPv6, assignment is strongly recommended on nibble boundaries, so that means /56.

Regards,
Bill Herrin
