[ppml] Policy Proposal: Decreasing Exponential Rationing of IPv4 IP Addresses - AC did not accept
info at arin.net
Tue Aug 28 10:56:03 EDT 2007
On 23 August 2007, the ARIN Advisory Council (AC) concluded its review
of the proposed policy 'Decreasing Exponential Rationing of IPv4 IP
Addresses' and did not accept it as a formal policy proposal. The AC did
not accept the proposal because it presents an approach, rather than
defines a policy. There are no details around how or where it adds to,
or alters, the current version of the NRPM.
During the initial review period the AC may decide to:
1) Accept the proposal as a formal policy proposal as written.
2) Postpone their decision regarding the proposal until the next
regularly scheduled AC meeting in order to work with the author.
3) Not accept the policy proposal.
In the event that the AC decides not to accept the proposal, then the
author may elect to use the petition process to advance the proposal.
For petition details see the section called "Petition Process" in the
ARIN Internet Resource Policy Evaluation Process which can be found at:
The deadline for the author to initiate a petition per the ARIN Internet
Resource Policy Evaluation Process is 40 days prior to the meeting; the
petition deadline for the ARIN XX Public Policy Meeting is 23:59 EDT, 7
September 2007. If the author chooses not to petition or the petition is
unsuccessful, then the proposed policy is closed. If a petition is
successful, then the proposal will be numbered and posted for discussion
and presented at ARIN's Public Policy Meeting.
