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

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)

measuring web similarity from dual-stacked hosts

Dear v6 WG, Measuring Web Similarity from Dual-stacked Hosts ------------------------------------------------ How similar are the webpages accessed over IPv6 to their IPv4 counterparts? – In situations where the content is dissimilar over IPv4 and IPv6, what factors contribute to the dissimilarity? To answer ^ we developed a tool (simweb) and deployed it on 80 geographically distributed dual-stacked SamKnows probes. A paper presenting results from the collected dataset got accepted recently. We just released the tool and the paper [a]. Thought to share it along. [a] http://goo.gl/sAsDcG Feedback most welcome! You may recall a presentation of this work at RIPE 72 [b]. [b] https://ripe72.ripe.net/archives/video/126 Abstract -------- We compare the similarity of webpages delivered over IPv4 and IPv6. Using the SamKnows web performance (webget) test, we implemented an extension (simweb) that allows us to measure the similarity of webpages. The simweb test measures against ALEXA top 100 dual-stacked websites from 80 SamKnows probes connected to dual-stacked networks representing 58 different ASes. Using a two months-long dataset we show that 14% of these dual-stacked websites exhibit a dissimilarity in the number of fetched webpage elements, with 94% of them exhibiting a dissimilarity in their size. We show that 6% of these websites announce AAAA entries in the DNS but no content is delivered over IPv6 when an HTTP request is made. We also noticed several cases where not all webpage elements (such as images, javascript and CSS) of a dual-stacked website are available over IPv6. We show that 27% of the dual-stacked websites have some fraction of webpage elements that fail over IPv6, with 9% of the websites having more than 50% webpage elements that fail over IPv6. We perform a causality analysis and also identify sources for these failing elements. We show that 12% of these websites have more than 50% webpage elements that belong to the same origin source and fail over IPv6. Failure rates are largely affected by DNS resolution error on images, javascript and CSS content delivered from both same-origin and cross-origin sources. These failures tend to cripple experience for users behind an IPv6-only network and a quantification of failure cases may help improve IPv6 adoption on the Internet. -- Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Postdoctoral Researcher Jacobs University Bremen, Germany ===================================

Hi there ;) Time flies, RIPE73 is less than two months away. If you'd like to present at IPv6 WG sessions in Madrid, or just have a suggestion for the agenda - please contact ipv6-wg-chairs(a)ripe.net. (If you could provide a short summary of your talk and how much time you need- it would help a lot to build an agenda and would be highly appreciated ;)) Thanks and see you in Madrid! --- On behalf of IPv6 WG Chairs, Jen Linkova aka Furry
