<div dir="ltr">If you operate a network with peering sessions, and you are forced to renumber your ASN, you either need to convince all of your peers to set up new sessions (which can be a lot of work, and usually means at least some of them will refuse/fail to do so), or you need to local-as prepend the old ASN onto your new one, resulting in a longer AS path over that session. Both outcomes are disruptive to a network's ability to maintain peering.<div><br></div><div>Given that there are valid technical and business justifications for needing to keep the same ASN on a network whose locus of control switches continents, I believe it is appropriate to allow organizations who need to do so to transfer administrative control of their ASN between RIRs, and therefore support this draft policy.<br></div><div><br></div><div><div>While it is certainly possible for some networks to easily renumber their ASN, that is not true of all networks, for valid technical reasons. I therefore do not find arguments of the "I've never needed to do that" or "I can't imagine why someone would need to do that" informative or convincing. To my mind, the only argument that would justify opposing ASN transfers would be one that details how such transfers would be burdensome to the RIRs or to the Internet community more generally, and would further show that such burden is greater than the benefit to those organizations it would help. As I, Job, and others have detailed the kind of organization that would be benefited by this proposal, it's not sufficient to assert that such organization do not (or should not) exist.</div><div><br></div></div><div>-Scott</div></div><br><div class="gmail_quote"><div dir="ltr">On Mon, Aug 13, 2018 at 3:36 PM Job Snijders <<a href="mailto:job@ntt.net">job@ntt.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>On Tue, 14 Aug 2018 at 01:23, Larry Ash <<a href="mailto:lar@mwtcorp.net" target="_blank">lar@mwtcorp.net</a>> wrote:<br></div><div><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Mon, 13 Aug 2018 14:47:09 -0700<br>

I agree with Owen, I just can't see a burning need. Renumbering seems to be a bugaboo that is just not that difficult.</blockquote><div dir="auto"><br></div><div dir="auto">Even if you don’t see a need, would you want to preclude others from transferring their resource if they concluded it is a requirement for their business operation?</div><div dir="auto"><br></div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I would think the transfer of the ASN would as costly, difficult and risky as migrating the resources onto a new ASN.</blockquote><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">I’m puzzled by your statement.
