[arin-ppml] A modest proposal for IPv6 address allocations

Agreed a /56 might be appropriate.

Earlier Owen appropriately corrected me for comparing a /48 v6 allocation to a class B v4 allocation but he actually enforced the point I was going to make.  Even a /48 allocation for small business or individual use is a bit ridiculous given conventional IP network architectures.  But one of our problems is that since we don't have any truly large scale deployments (something at least into the 100K nodes size), we don't know what a real IPv6 network may consume.

Take care
