<div dir="ltr">Thanks, Scott,<div><div><br></div><div>Are we energetically agreeing? You scared me there for a second. /48s are excluded, unless they are part of a "subdelegation of any size that will be individually announced". Yes.</div><div><br></div><div>How is that defined by the way? Will be individually announced in 2 years, 2 days, right now? </div><div><br></div><div>On another matter, this problem statement has been making me uneasy all along, but because it was only required to be clear and in scope to be accepted as Draft Policy, it was not appropriate for me to object. This seems like as good a time as any to address some concerns, which are my opinions only.</div><div><br></div><div>"Current ARIN policy has different WHOIS directory registration requirements for IPv4 vs IPv6 address assignments."</div><div><br></div><div>This is a correct statement! It is not a problem however, nor is it sufficient motive for trying to solve a problem, per se.</div><div><br></div><div>"IPv4 registration is triggered for an assignment of any address block equal to or greater than a /29 (i.e., eight IPv4 addresses).</div><div> In the case of IPv6, registration occurs for an assignment of any block equal to or greater than a /64," </div><div><br></div><div>Two facts. The second is undoubtedly a great pity, but to entangle these logically is a fallacy of inconsistency, specifically a false equivalence. These two facts are unrelated. It does not help the case to try to make them interdependent. And it is not needed. All that is being attempted is to modify V6 SWIP requirements. Do that. And DO NOT settle on 8 subnets. </div><div><br></div><div>"which constitutes one entire IPv6 subnet and is the minimum block size for an allocation."<br></div><div><br></div><div>I think I'm looking at current text. How did this make it this far? One ENTIRE IPV6 subnet? There are lots of entire V6 subnets all the way from /0 to /128. What does that have to do with anything? And, yeah, the SWIP boundary being the so called "minimum" allocation seems broken, but that is its own thing.</div><div><br></div><div>"There is no technical or policy rationale for the disparity, which could serve as a deterrent to more rapid IPv6 adoption."</div><div><br></div><div>Possibly true, but irrelevant. There is no technical or policy rationale for them being alike either, nor is there any reason to suppose that if they were, folks would adopt V6 faster. SWIPing /64 is definitely wrong for V6. Concentrate on that. We can make policy for V6 without needing to refer to V4.</div><div><br></div><div>"The purpose of this proposal is to eliminate the disparity and corresponding adverse consequences."</div><div><br></div><div>With respect, it is not. The disparity does not qualify as a logical motive. The brokenness of SWIPing /64s does not require injustice and if /64 SWIPing is a deterrent to V6 adoption, that is its own good and sufficient reason. If you had to refer to an analogy, you could say, "SWIPing /64s is analogous to SWIPing /32s and that seems dumb".</div><div><br></div><div>So all you need is:</div><div><br></div><div>Problem Statement: SWIPing IPV6 /64s is the problem. The purpose of this proposal is to pick a different number. </div><div><div><br></div><div>Policy statement:</div><div> 1) Alter section 6.5.5.1 "Reassignment information" of the NRPM to strike "/64 or more addresses" and change to "/47 or more addresses, or subdelegation of any size that will be individually announced,"</div><div>and </div><div> 2) Alter section 6.5.5.3.1. "Residential Customer Privacy" of the NRPM by deleting the phrase "holding /64 and larger blocks"</div></div><div><br></div><div>BUT. These observations do not appear to have any effect one way or the other on the policy text. To me, picking a different number does not have anything to do with disparity, but so what? Changing the IPV6 SWIP threshold is not unfair and partial if someone makes unfounded assertions regarding linkages between v4 and V6. And it is not technically unsound to make fallacious observations if they are kind of orthogonal to the meat of the matter.<br></div><div><br></div><div>So, still support. I'd rather see it simpler, but I guess I can tolerate a little hand waving.</div><div><br></div><div>Writing solely on my own behalf,</div><div><br></div><div>John Springer<br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jul 21, 2017 at 9:15 PM, Scott Leibrand <span dir="ltr"><<a href="mailto:scottleibrand@gmail.com" target="_blank">scottleibrand@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><span class=""><div>On Jul 21, 2017, at 8:31 PM, John Springer <<a href="mailto:3johnl@gmail.com" target="_blank">3johnl@gmail.com</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">I support this Draft Policy as re-written.<div><br></div><div>I shared the author's distaste for the requirement that IPV6 /64s be SWIP'd, but was not reassured when the discussion veered to consider prefixes between /48 and /64.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> Currently, assignments of /29 or more of IPv4 space (8 addresses) require registration<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> The greatest majority of ISP customers who have assignments of IPv4 space are of a single IPv4 address which do not trigger any ARIN registration requirement
when using IPv4.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> This is NOT true when these same exact customers use IPv6, as assignments of /64 or more of IPv6 space require registration.
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> Beginning with RFC 3177, it has been standard practice to assign a minimum assignment of /64 to every customer end user site, and less is never used.
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> This means that ALL IPv6 assignments, including those customers that only use a single IPv4 address must be registered with ARIN if they are given
the minimum assignment of /64 of IPv6 space. <u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> This additional effort may prevent ISP's from giving IPv6 addresses because of the additional expense of registering those addresses with ARIN, which
is not required for IPv4.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#993366"> The administrative burden of 100% customer registration of IPv6 customers is unreasonable, when such is not required for those customers receiving
only IPv4 connections.<u></u><u></u></span></p>
