[arin-ppml] Policy Proposal: Equitable Distribution of IPv4 Resources before IPv4 Run out

Thu May 22 20:00:49 EDT 2008

Hello Owen:

The intent was certainly not to exclude end users.  Data concerning allocations to end users shows only the number of processed requests and doesn't break out the actual allocation sizes.  I assume that the data necessary to include the end users is available and can be incorporated into the distribution model.

Regards,

Mike
