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

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

[request]: host a probe for v6 measurements
by Bajpai, Vaibhav 08 Oct '16

08 Oct '16

Dear v6-WG, We are (again) looking for volunteers with native IPv6 lines at home to help us in our v6 measurement research. Background ---------- We are interested in measuring IPv6 performance from home. Our measurement tests come bundled with a SamKnows probe. We currently have ~80 SamKnows probes deployed over the globe. The google map [a] shows where these probes are currently deployed. [a] https://goo.gl/Jhz49o |------------------------+------| |----------+------| | RESIDENTIAL | 55 | | RIPE | 42 | | NREN / RESEARCH | 11 | | ARIN | 29 | | BUSINESS / DATACENTER | 09 | | APNIC | 07 | | OPERATOR LAB | 04 | | AFRINIC | 01 | | IXP | 01 | | LACNIC | 01 | |------------------------+------| |----------+------| This is the distribution of our current deployment by network type and by RIR region. Please see [b] for more details: [b] http://goo.gl/PwD4yN Request ------- If you receive native IPv6 at home (or know someone who does), it would be great if you can host a SamKnows probe for us. The probe will run standard SamKnows tests and our IPv6 tests. We prefer measuring from home networks and over a longitudinal period of time (say multiple years). Please see [c] if you'd like to learn more about the SamKnows platform. [c] http://vaibhavbajpai.com/documents/papers/proceedings/lsmp-comst-2015.pdf Action ------- Let me know if you’re interested, and I can share details on how to get the probe to you. We only have limited number of SamKnows probes. We will process the requests on first come first serve basis. Would be nice if you can share these details in your response: - v4 and v6 ASN (or provider name) - location (city-level granularity) - network type (see above table for an example) - shipment address Research Impact --------------- For more details, please see: Measuring Web Similarity from Dual-stacked Hosts Conference on Network and Service Management (CNSM) 2016. http://vaibhavbajpai.com/documents/papers/proceedings/dualstack-simweb-cnsm… Measuring the Effects of Happy Eyeballs Applied Networking Research Workshop (ANRW) 2016. http://vaibhavbajpai.com/documents/papers/proceedings/dualstack-he-anrw-201… Measuring YouTube from Dual-Stacked Hosts Passive and Active Measurement Conference (PAM) 2015. http://vaibhavbajpai.com/documents/papers/proceedings/dualstack-youtube-pam… IPv4 versus IPv6 - Who connects faster?

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
by Bajpai, Vaibhav 04 Sep '16

04 Sep '16

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 ===================================

IPv6 Best Practice Forum
by Michael Oghia 27 Jul '16

27 Jul '16

Dear colleagues, Building on last year's IGF Best Practice Forum (BPF) on creating an enabling environment for IPv6 <http://www.intgovforum.org/cms/documents/best-practice-forums/creating-an-e…>, we are now focusing this year's IPv6 BPF work on how to best encourage and support IPv6 adoption (for more information, see: Scope and Goals <http://www.intgovforum.org/cms/documents/best-practice-forums/798-scope-and…> ). The IPv6 BPF is a consensus-driven, bottom-up, and inclusive collaborative effort, one that brings together professional expertise from across stakeholder groups in order to generate a practical, constructive, and relevant outcome document. We are currently soliciting feedback and brainstorming ideas, especially related to economic elements of IPv6 adoption and business cases: https://docs.google.com/document/d/1C7z8MRVBOmBsuWxpl8YivXZWFvksKCq0_ul7TlF… If you are not already involved, I encourage you to add suggestions to the document, share it among your networks, and contact Izumi Okutani, our MAG coordinator, or Wim Degezelle, the IPv6 BPF project manager, for more information or if you have any questions. Additionally, you can sign up for the mailing list at: http://mail.intgovforum.org/mailman/listinfo/bp_ipv6_intgovforum.org. Kind regards, -Michael __________________ Michael J.

Enterprise (Rabobank) on IPv6
by Sander Steffann 26 Jul '16

26 Jul '16

Hi, For those of you who need some serious examples of enterprises doing IPv6 so you can convince other enterprises: today there is a new example to follow, rabobank.nl :-) Rabobank is one of the largest banks of the Netherlands (and according to i.e. http://www.accuity.com/useful-links/bank-rankings/ even in the top-50 of largest banks in the world). Banks are often known for being cautious and conservative, so a major bank deploying IPv6 on their main website might take away some reluctance at other enterprises. Cheers! Sander
