And I think that it would make sense to have a discussion on this with a policy proposal on the table. <o:p></o:p> <o:p> </o:p> As you mentioned, this has been brought up multiple times already, so it would be good to see if we can get this sorted. <o:p></o:p> <o:p> </o:p> It would be nice if the AP-WG members could provide some insight if the would support (or not) a policy proposal as suggested. <o:p></o:p> <o:p> </o:p> Regards,<o:p></o:p> Speaking as one of the Co-Chairs, <o:p></o:p> Erik Bais <o:p></o:p> <o:p> </o:p> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm"> From: address-policy-wg <address-policy-wg-bounces@ripe.net> on behalf of Edwin Verheul <edwin.verheul@surf.nl> Date: Thursday, 17 November 2022 at 16:24 To: "address-policy-wg@ripe.net" <address-policy-wg@ripe.net> Subject: [address-policy-wg] Minimum size for IPv4 temporary assignments<o:p></o:p> </div> <div> <o:p> </o:p> </div> Dear colleagues of the Address Policy Working Group,<o:p></o:p> <o:p> </o:p> During (my first!) RIPE85 there was short discussion about the minimal size for IPv4 temporary assignments in this workgroup.<o:p></o:p> The policy for temporary IPv4 assignments requires you to use 50% of the assigned addresses [1].<o:p></o:p> This requirement pushes events or experiments into smaller assignments less than /24’s, which are mostly unroutable on the internet.<o:p></o:p> <o:p> </o:p> This is mentioned before by Marco Schmidt [2] in October 2022 and Randy Bush [3] in Januari 2022.<o:p></o:p> It looks to me this is a legitimate reason to propose this in a policy change:<o:p></o:p> <o:p> </o:p> <ul style="margin-top:0cm" type="disc"> <li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo3">Temporary IPv4 assignments ≤ /24 should NOT subject to the 50% usage requirement;<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo3">Only smaller assignments will be handed out if the assignee is explicitly willing to have (sub optimal) unroutable IP space on the internet;<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l1 level1 lfo3">If it is required by the assignee to advertise multiple subnets, the policy should allow to assign multiple /24’s( or a bigger assignment, so the assignee can split and advertise by themselves).<o:p></o:p></li></ul> <o:p> </o:p> Elvis Velea and myself are willing to (co) author this proposal. We will do our best to hand in the proposal by the end of this year.<o:p></o:p> <o:p> </o:p> Any thoughts on this?<o:p></o:p> <o:p> </o:p> Kind regards,<o:p></o:p> <o:p> </o:p> Edwin Verheul<o:p></o:p> SURF <o:p></o:p> AS1103<o:p></o:p> <o:p> </o:p> [1] <a href="https://www.ripe.net/publications/docs/ripe-587#utilisation-rates">https://www.ripe.net/publications/docs/ripe-587#utilisation-rates</a><o:p></o:p> [2] <a href="https://www.ripe.net/ripe/mail/archives/address-policy-wg/2022-October/013598.html"> https://www.ripe.net/ripe/mail/archives/address-policy-wg/2022-October/013598.html</a><o:p></o:p> [3] <a href="https://www.ripe.net/ripe/mail/archives/address-policy-wg/2022-January/013438.html"> https://www.ripe.net/ripe/mail/archives/address-policy-wg/2022-January/013438.html</a><o:p></o:p> </div> </body> </html>
