<div>Hi Owen,</div>
<div> </div>
<div>Yes, it was a dense read, I was hoping that since Edelman advised ARIN that
the spartan concept had been discussed at some level there, and some
simplification of the concepts elucidated in the paper could be forthcoming from
that direction.</div>
<div> </div></div></div></div></blockquote><div><br></div>I believe this is research Mr. Edelman pursued after (and likely as a result of) his advising ARIN in the development of NRPM 8.3. I certainly would support the idea of ARIN bringing Mr. Edelman back to discuss this with the community.</div><div><br><blockquote type="cite"><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space" dir="ltr"><div dir="ltr"><div style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt">
<div>However, I find the price graphs baffling, and the duration of
extinguishment and protections against agents adopting multiple identities to be
subjects for more discussion.</div>
</div></div></div></blockquote><div><br></div>Definitely. I would not support an extinguishment period less than the maximum duration allowed for justified need under policy.</div><div><br><blockquote type="cite"><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space" dir="ltr"><div dir="ltr"><div style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt"><div> </div>
<div>Of course this begs the question of transfer restrictions driving unbooked
transfers, but still the concept is interesting.</div>
</div></div></div></blockquote><div><br></div>I think for the reasons outlined in the paper and the other reasons already well discussed on this list, those are of less concern than some would have us believe. I think the likelihood of unbooked transfers achieving long-term success on a wide scale is rather small.</div><div><br><blockquote type="cite"><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space" dir="ltr"><div dir="ltr"><div style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt"><div> </div>
<div>I don’t find the social cost of table growth to be as high as the authors
believe, I don’t foresee fragmentation happening to such an extent as to damage
stability, but I realize this is just opinion at this stage.</div>
</div></div></div></blockquote><div><br></div>I'm actually beginning to believe that IPv4 table fragmentation may become the biggest IPv6 driver relatively soon, so, I'm willing to agree that perhaps continuing to make efforts to artificially constrain IPv4 table growth may, in fact, be unwise.</div><div><br><blockquote type="cite"><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space" dir="ltr"><div dir="ltr"><div style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt"><div> </div>
<div>As the authors state, this is an unusual market and it may be fruitful for
economists to apply their tools.</div>
</div></div></div></blockquote><div><br></div>Or, perhaps, it is an unusual market and their tools will prove wholly inadequate to the task at hand until they have experience enough with the market to develop applicable tools. Unfortunately, only time will tell.</div><div><br></div><div>Note, I'm not saying that the above is the case, just saying that there are at least two possibilities worthy of consideration.</div><div><br></div><div>Owen</div><div><br><blockquote type="cite"><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space" dir="ltr"><div dir="ltr"><div style="FONT-FAMILY: 'Calibri'; COLOR: #000000; FONT-SIZE: 12pt"><div> </div>

<div><span style="WHITE-SPACE: pre" class="Apple-tab-span"></span>Thanks for
posting that. I found it largely indecipherable, but, I confess ignorance in
both the math involved and the theoretical economics.</div>
<div> </div>
<div><span style="WHITE-SPACE: pre" class="Apple-tab-span"></span>I do find the
assumption that the price of IPv4 addresses declines post exhaustion rather
startling vs. the reality that everyone expects IPv4 addressing prices will
increase until IPv4 is obsoleted.</div>
<div> </div>
<div><span style="WHITE-SPACE: pre" class="Apple-tab-span"></span>I find the
spartan rule idea novel and interesting. I don't believe it is a viable
substitute for needs-basis, but, I do believe it might be a worth-while
additional constraint.</div>
