<TITLE>Notice: ARIN AC Disposition of IPv4 Soft Landing policy proposal</TITLE>
</HEAD>
<BODY>
<!-- Converted from text/rtf format -->
<P><FONT SIZE=2 FACE="Arial">Hello,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">The ARIN Advisory Council at its May 17 meeting chose to 'work with the author', David Conrad, to potentially modify the IPv4 Soft Landing policy proposal rather than accept it 'as is'. This AC decision was based upon the ppml discussion leading up the AC meeting on May 17.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">David Conrad has agreed to rework the policy proposal to incorporate feedback from the ppml, ARIN staff and ARIN counsel and the AC.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Following was the analysis presented and forming the basis for the AC determination.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">*************************</FONT>
<BR><FONT SIZE=2 FACE="Arial">PPML summary:</FONT>
<BR><FONT SIZE=2 FACE="Arial">In excess of 60 (mostly) relevant postings from about 20 entities (as of 1pm Central)</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Declarations:</FONT>
<BR><FONT SIZE=2 FACE="Arial">For - 4</FONT>
<BR><FONT SIZE=2 FACE="Arial">Against - 4</FONT>
<BR><FONT SIZE=2 FACE="Arial">On the fence - 1</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Primary points:</FONT>
<BR><FONT SIZE=2 FACE="Arial">Staging provides gradual and transparent increases in v4 efficiency requirements and v6 engagement. </FONT>
<BR><FONT SIZE=2 FACE="Arial">Looks to be too many stages given 'new' end-date provided by Geoff Huston (31 Dec '09) - this view supported by author</FONT>
<BR><FONT SIZE=2 FACE="Arial">Is it even needed, or can it work given current end-date suggested by Geoff Huston?</FONT>
<BR><FONT SIZE=2 FACE="Arial">Be better to abandon proposal and focus on educational outreach and 'tools' to support v6 adoption</FONT>
<BR><FONT SIZE=2 FACE="Arial">Focuses ISP only - author said he could include enduser portion by popular demand, didn't seem to be much</FONT>
<BR><FONT SIZE=2 FACE="Arial">'Forces' the investment of ISPs in v6 infrastructure and perhaps marketing to get new ration of v4 - is this pressure part of ARIN's charter?</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Proposal may need to be global policy with some skepticism that all regions would adopt same-text policy in (at least) a timely fashion </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Suggestion that ARIN or 3rd party would do a formalized audit with majority opinion that requester would pay</FONT>
<BR><FONT SIZE=2 FACE="Arial">Cost of audit might make expensive secondary market for IPv4 more reasonable…issue of auditor certification issues raised</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Concern that implementation might cause ARIN to review previous allocations in light of IPv6 hurdles as part of a reclamation program</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Suggestion that if/when edits to proposal are finished, a ppml 'survey' should be used to get better sense of consensus - author agrees</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Proposal as is, has adequate clarity of proposal statement and rationale and is from an author likely to present it personally</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Author also seems willing to rewrite to increase acceptance/appropriateness</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">My recommendation to AC: Work with the author - given the interest in this topic overall</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Considerations to abandon: Legal issues surrounding audit and requiring ISP to adopt a technology they are not asking for. Possibly outside the scope of ARIN's role of number resource stewards. Impractical if it cannot be adopted globally in similar fashion. May be better addressed by educational and media outreach.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">*****************************</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Thank you all for your interest an involvement with ARIN public policy evaluation. Please continue to express your opinions and suggestions on how the IPv4 Soft Landing proposal could be modified to make it most valuable to the community. And, the Advisory Council will be most appreciative of your declaration For or Against the proposal as this helps removes subjective assessment of consensus.</FONT></P>
