<p class="MsoNormal">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.<o:p></o:p></p>

<div>
<p class="MsoNormal">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.<o:p></o:p></p>
