[arin-ppml] Draft Policy ARIN-2013-2: 3GPP Network IP Resource Policy

[Scott Leibrand]

That is my understanding of the author's intent, yes. IPv6 policy does not have the problem described, because even a /32 has more than enough addresses for all the mobile devices on a single network. Also, current IPv6 policy allows for larger subnets to be allocated to ensure appropriate sized subnets are given to each customer, and to provide for hierarchical allocation. 

When we write the policy text for any preferred solution, we'll be sure to place it in the appropriate section and make clear that it applies to IPv4 only. The "policy statement" is more of an outline at this point: we need to decide which solution is preferred before settling on policy text.
