Yes, yes, only one registrant has thus far had the chutzpah to seek<br>
and acquire a /16. I have already acknowledged the truth of that<br>
claim; you need not continue repeating it.<br>
<br>
Perhaps you could stop deflecting the question I asked you in return:<br>
Do you, David Farmer, believe there exists a justification for an<br>
*initial* allocation of a /16 of IPv6 addresses which would withstand<br>
public scrutiny? An allocation to an organization which has never<br>
before held ARIN IPv6 addresses. If you do, would you care to offer us<br>
such a hypothetical to examine?<br></blockquote><div> </div><div><div>I considered this question back in 2011 when the question of /16 or /20 came up in the discussion of ARIN-2011-3. I concluded it was possible to justify a /16. Let me put the question slightly differently: Is it possible to justify more than a /20? There were already /19s allocated by other RIRs, so I concluded that it is possible to justify more than a /20. I also believe nibble alignment is important, so I support /16 as the maximum allocation. Nevertheless, such /16 allocation should be rare; one in a decade aligns with that belief.</div><div><br></div><div>However, those who think it is impossible to justify a /16 for an initial allocation should support this policy.</div><div><br></div></div><div>Thanks.</div></div><div><br></div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature">===============================================<br>David Farmer <a href="mailto:Email%3Afarmer@umn.edu" target="_blank">Email:farmer@umn.edu</a><br>Networking & Telecommunication Services<br>Office of Information Technology<br>University of Minnesota <br>2218 University Ave SE Phone: 612-626-0815<br>Minneapolis, MN 55414-3029 Cell: 612-812-9952<br>=============================================== </div></div>
