Happy Eyeballs bias
by Sander Steffann 27 Oct '16

27 Oct '16

Hi, Very good presentation on Happy Eyeballs at the WG session today. It might indeed be true that lowering the HE "head start" for IPv6 from 300ms to 150ms might cause a slight increase in performance. However, as Geoff Huston pointed out, HE is not about getting the best performance, it's meant to move traffic to IPv6 (so IPv4 traffic will go down, and we can know when we can turn off IPv4) without breaking the user experience when IPv6 is broken. It was (and still is) an important argument for website owners to be comfortable enough to actually deploy IPv6 and not be too worried about client experience breaking. But it is also hiding IPv6 brokenness, removing an incentive for website owners to actually fixing IPv6 errors and causing IPv6 to be taken less seriously... So, how about we go the other way. We want IPv6 to be taken more seriously. What about if we change the algorithm the other way over time: give IPv6 more and more of a head start. That way IPv6 stability and performance become more important over time, without causing brokenness. Something like: HE head start = 300 + (months after 2017-01-01) * 30 That would provide some incentive to make sure that IPv6 is properly deployed and managed. Cheers, Sander

Chair selection: call for candidates
by Anna Wilson 26 Oct '16

26 Oct '16

Hello all, The working group selected Jen, Benedikt and myself as co-chairs at RIPE69 in November 2014. At RIPE70, we adopted this procedure for replacing chairs: https://www.ripe.net/ripe/mail/archives/ipv6-wg/2015-May/002615.html This provides for a three year term. Since all three of us were selected at the same meeting, our terms would expire simultaneously in late 2017. To encourage continuity, I plan to step down next month at RIPE73. We therefore call for candidates for the post of IPv6 working group chair. If you would like to stand for selection, please announce so to the mailing list. The closing date for candidates is 23:59 UTC on Friday 21st October 2016. (The Friday before the RIPE73 meeting.) As per the procedure, the selection itself will take place during the working group session at RIPE73. Best regards, Anna -- Anna Wilson, Service Desk Manager web: www.heanet.ie HEAnet Ltd, 5 George's Dock, IFSC, Dublin 1 tel: +353-1-660-9040 Registered in Ireland, no 275301 fax: +353-1-660-3666

This should be a general statement on the IPv6 readiness of IXPs in the world, and briefly discuss motivation and challenges. I found a Euro-IX statement <http://www.netnod.se/sites/default/files/Euro-IX_IPv6_press.pdf> from June 2011 that announced that all Euro-IX members are IPv6 ready and enabled. Does anyone knows of recent updates or statements on the IPv6-readines of IXPs? FYI the BPF IPv6 draft is available on google docs ( link <https://docs.google.com/document/d/1Z60lBcIk7U3LAFEK9V7dIQ11OWFx71zqmMAcs9u…> ).

New on RIPE Labs: IPv6 and DNS (by Geoff Huston)
by Mirjam Kuehne 20 Oct '16

20 Oct '16

Dear colleagues, Please find this new post by Geoff Huston on RIPE Labs: https://labs.ripe.net/Members/gih/ipv6-and-the-dns "The exhortations about the Internet’s prolonged transition to version 6 of the Internet Protocol continue, although after some two decades the intensity of the rhetoric has faded and, possibly surprisingly, it has been replaced by action in some notable parts of the Internet. But how do we know there is action? How can we tell whether, and where, IPv6 is being deployed in today’s Internet?" Kind regards, Mirjam Kuehne RIPE NCC

New on RIPE Labs: Supporting IPv6 Deployment Through Policy
by Marco Schmidt 11 Oct '16

Dear colleagues, It was about a year ago that the RIPE community reached consensus on a policy proposal that introduced additional criteria for initial IPv6 allocations. We thought it was time to look back the origins of this proposal and see how the change has worked out since: https://labs.ripe.net/Members/marco_schmidt/supporting-ipv6-deployment-thro… Regards, Marco Schmidt Policy Development Officer RIPE NCC Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

1. Re: RIPE72 IPv6 WG: call for presentations (Benedikt Stockebrand) Hello to all I think the basic work for ISPs in concern to IPv6 is covered. But i miss the topics to be addressed if you want to migrate from a IPv4 Microsoft Active domain using company to an system where most server in an enterprise could by just IPv6 only and use technologies like NAT46 ( SIIT-DC ) or similar to still make IPv4 only windows clients happy. Switching an enterprise with location around the global from a "we donot route any IPv6 traffic across our WAN Links" "most servers have IPv6 disabled" to We start IPv6 routing partially and enable partial IPv6 support on servers in a Microsoft ADS environment seems not covered in most IPv6 covering websites and presentations. Maintaining dual stack for the datacenters is just painfull and there should be a "single" device in the form of NAT46/SIIT/SIIT-DC in front of each server area. I am not sure that Active directory is ready for that. We are currently moving a complete test ads domain into a Testlab with locations in AT/CN/FI/US into dualstack and here we accept a "not working" during migration and i also hope we can move some servers into a IPv6 only area of those networks. But for a production move we need to be shure that a partial enabling of Dualstack and IPv6 only networking for servers does not break things. Any ideas or links which could help us here? best regards Christian Bretterhofer https://andritz.me ( one Testlab DMZ)
