ARIN received the following policy proposal and is posting it to the
Public Policy Mailing List (PPML) in accordance with Policy Development
Process.
This proposal is in the first stage of the Policy Development Process.
ARIN staff will perform the Clarity and Understanding step. Staff does
not evaluate the proposal at this time, their goal is to make sure that
they understand the proposal and believe the community will as well.
Staff will report their results to the ARIN Advisory Council (AC) within
10 days.
The AC will review the proposal at their next regularly scheduled
meeting (if the period before the next regularly scheduled meeting is
less than 10 days, then the period may be extended to the subsequent
regularly scheduled meeting). The AC will decide how to utilize the
proposal and announce the decision to the PPML.
In the meantime, the AC invites everyone to comment on the proposal on
the PPML, particularly their support or non-support and the reasoning
behind their opinion. Such participation contributes to a thorough
vetting and provides important guidance to the AC in their deliberations.

TEMPLATE: ARIN-POLICY-PROPOSAL-TEMPLATE-2.0
1. Policy Proposal Name: /24 End User Minimum Allocation Unit
2. Proposal Originator: Owen DeLong
3. Proposal Version: 0.9
4. Date: 8/3/09
5. Proposal type: new
6. Policy term: permanent
7. Policy statement:
Replace section 4.3.2.2 of the NRPM with the following:
4.3.2.2 Multihomed Connection
For end-users who demonstrate an intent to announce the requested
space in a
multihomed fashion to two or more distinct providers, the minimum
block of IP
address space assigned is a /24. If assignments smaller than a /24
are needed,
multihomed end-users should contact their upstream providers. When
prefixes are
assigned which are longer than /20, they will be from a block
reserved for that
purpose so long as that is feasible. End-users may not receive a
block smaller
than /22 under this policy if they already have resources from ARIN,
except as
specified in section 4.3.6.2.
Renumber the existing paragraph under the 4.3.6 to
4.3.6.1 Utilization requirements for additional Assignment
Add the following paragraph 4.3.6.2
4.3.6.2 Replacement assignments for small multi-homers
Any end-user that possesses an assignment smaller than /22 under any
part of
section 4.3 shall not be able to get an additional assignment unless
they agree
to return all existing assignments within 12 months of receiving a
new assignment.
The new assignment shall be sized to accommodate their existing
utilization in
addition to their justified additional growth space under section
4.3.6.1.
The common cases for this are expected to be a /24 returned after
receipt of a /23,
or a /23 returned after receipt of a /22.
8. Rationale:
This policy attempts to incorporate the recent and historical
discussions of
policy for multi-home users on PPML. The intent is to provide as fair
a process
as possible for multi-homed organizations down to the smallest
feasible size
while still preserving some control over growth in the routing table.
It has been repeatedly noted that /24 multi-homers exist today with
PA space
and still occupy a routing table slot, so, it is unlikely that moving
this
boundary to /24 would significantly impact the routing table.
By requiring smaller assignments to renumber and return, rather than
add more
small blocks to their assignments, this policy seeks to further
reduce the
chances of unnecessary growth in the routing table and encourage good
aggregation
where possible.
9. Timetable for implementation: Immediate
END OF TEMPLATE
