[ppml] Proposed policy - Defining Utilization of IPv4 addresses

[Charles Scott]

PPML:
  This would seem to be a necessary and well constructed policy. The only 
glitch I see in it is the use of "utilized addresses" in "5". Since we're 
talkng about addresses that are assigned or allocated to a customer as 
fully utilized for the purpose of this policy, "5" could be changed to say 
it more clearly.

5. The utilization rate of an address block is calculated as the 
   number of addresses assigned or allocated out of that address 
   block divided by the total number of addresses in the block.

  Other than that, I think I like it.
