On 20 September 2007, the ARIN Advisory Council (AC) concluded its
review of the proposed policy 'Modification to Reverse Mapping Policy'
and did not accept it as a formal policy proposal. The AC provided the
following explanation of their decision:
"Although the Advisory Council is sympathetic to your cause we have
moved to not accept your proposal: Modification to Reverse Mapping
Policy. The reason we have chosen this motion is because detailed
operational techniques do not belong in the the NRPM. Although this may
have occurred in the past, we are taking measures to ensure that we move
detailed operations into staff process and not the NRPM. We believe
moving forward that the best way to suggest and or change operational
process is through the ARIN Consultation and Suggestion Process."
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 XXI Public Policy Meeting is 23:59 EDT,
27 February 2008. 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.

> Unfortunately, the policy does not cover the situation of a so-called
> partially lame delegation. That is, some of the in-addr.arpa zones
> belonging to the network registration return a valid SOA upon testing,
> and some do not. Even if only one /24 in-addr.arpa reverse tests comes
> back as lame, it is my opinion that this still taints the reputation of
> entire network registration. IPs belonging to that lame in-addr.arpa
> zone will cause query timeouts to 3rd party dns resolvers, both public
> and private. These excessive timeouts in my opinion can harm the overall
> well-being of reverse dns functionality throughout the internet. The
> only way to prevent such harm is for ARIN to not delegate reverse
> authority to the so-called partially lame dns server as registered in
> whois. That is the purpose of this policy proposal, to consider partial
> lameness with the same prejudice as traditionally defined lameness.
> Org's who are partially lame should be contacted by ARIN and lame
> in-addr.arpa zones should be resolved as the procedures per
> "http://www.arin.net/reference/ lame_delegations.html" dictate.
