Policy Proposal 2004-1: Defining Utilization of IPv4 Addresses
Author: Michael Dillon
Author's Organization: Radianz, Inc.
Policy term: permanent
Policy statement:
1. When an ISP applies for IPv4 address space, ARIN analyzes the
utilization rate of any existing IPv4 address blocks allocated
to the ISP.
2. For the purposes of calculating the utilization rate of ARIN
allocations, any IPv4 address range that is assigned or allocated
by the ISP to another organization will be counted as utilized if
it meets the following two conditions.
3. The assigned or allocated address range must be of a size that is
justified by ARIN policy.
4. The ISP must require the other organization to use their addresses
efficiently, in particular by using VLSM and CIDR technologies.
5. The utilization rate of an address block is calculated as the
number of utilized addresses divided by the total number of
addresses in the block.
Rationale:
Currently, there is no clear definition of utilization in ARIN's IPv4
policy. The result is that different organizations interpret this in
different ways. This policy change is an attempt to level the playing
field so that noone has an unfair competitive advantage due to the
vagueness of the policy.
This policy change only provides a clear definition for the utilization
rate of address blocks allocated by ARIN to ISPs. It does not address
the utilization rate of address blocks assigned to end users which
would presumably be calculated differently by counting end devices,
network and broadcast addresses.
Timetable for implementation: 30 days after ratification
