<p class="MsoNormal" style="margin-bottom:12.0pt">An interesting question came up on Tuesday in the ARIN IRR Roadmap at NANOG. Essentially, what is the intended semantics of Origin AS? See timestamp 20:14 to 21:04 in the following video;<br>
<br>
<a href="https://youtu.be/tsWq_LgNS5s">https://youtu.be/tsWq_LgNS5s</a><br>
<br>
Some background; Section 3.5 of the NRPM, originally Policy ARIN-2006-3, specifies the creation of what is now the "Origin AS" field in ARIN's registry, see;<br>
<br>
<a href="https://www.arin.net/policy/nrpm.html#three5">https://www.arin.net/policy/nrpm.html#three5</a><br>
<a href="https://www.arin.net/policy/proposals/2006_3.html">https://www.arin.net/policy/proposals/2006_3.html</a><br>
<br>
So back to the question; "are you allow to announce any more specifics based on the Origin AS?"<br>
<br>
Note the last sentence of section 3.5.1 says the following;<o:p></o:p></p>
</div>
</div>
</div>
</div>
<blockquote style="margin-left:30.0pt;margin-right:0in">
<div>
<div>
<div>
<div>
<p class="MsoNormal">This additional field will be used to record a list of the ASes that the user permits to originate address prefixes within the address block.<o:p></o:p></p>
</div>
</div>
</div>
</div>
</blockquote>

<p class="MsoNormal"><br>
While the policy doesn't formally specify the semantics for this field, based on the above sentence, I personally have to conclude that the policy intends that more specifics should be permitted based on the "Origin AS" filed.<br>
<br>
Does anyone read this differently?<br>
<br>
Do we need to further clarify this in the policy?<br>
<br>
Thanks.<o:p></o:p></p>
