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

New on RIPE Labs: Can You Make IPv6 Work Commercially?
by Mirjam Kuehne 07 Jul '16

07 Jul '16

Dear colleagues, Large scale IPv6 deployments suggest that IPv6 is at least a technical success, the technology works. Time to visit the other important question: does it work commercially. Does IPv6 really come with a positive business case? We are about to find out, if you help us...

Fwd: [v6ops] RFC 7872 on Observations on the Dropping of Packets with IPv6 Extension Headers in the Real World
by Fernando Gont 28 Jun '16

FYI -------- Forwarded Message -------- Subject: [v6ops] RFC 7872 on Observations on the Dropping of Packets with IPv6 Extension Headers in the Real World Date: Tue, 21 Jun 2016 16:57:35 -0700 (PDT) From: rfc-editor(a)rfc-editor.org To: ietf-announce(a)ietf.org, rfc-dist(a)rfc-editor.org CC: v6ops(a)ietf.org, rfc-editor(a)rfc-editor.org A new Request for Comments is now available in online RFC libraries. RFC 7872 Title: Observations on the Dropping of Packets with IPv6 Extension Headers in the Real World Author: F. Gont, J. Linkova, T. Chown, W. Liu Status: Informational Stream: IETF Date: June 2016 Mailbox: fgont(a)si6networks.com, furry(a)google.com, tim.chown(a)jisc.ac.uk, liushucheng(a)huawei.com Pages: 15 Characters: 30924 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-v6ops-ipv6-ehs-in-real-world-02.txt URL: https://www.rfc-editor.org/info/rfc7872 DOI: http://dx.doi.org/10.17487/RFC7872 This document presents real-world data regarding the extent to which packets with IPv6 Extension Headers (EHs) are dropped in the Internet (as originally measured in August 2014 and later in June 2015, with similar results) and where in the network such dropping occurs. The aforementioned results serve as a problem statement that is expected to trigger operational advice on the filtering of IPv6 packets carrying IPv6 EHs so that the situation improves over time. This document also explains how the results were obtained, such that the corresponding measurements can be reproduced by other members of the community and repeated over time to observe changes in the handling of packets with IPv6 EHs.

measuring the effects of happy eyeballs
by Bajpai, Vaibhav 22 Jun '16

22 Jun '16

Dear v6 WG, Measuring the Effects of Happy Eyeballs --------------------------------------- A paper on measuring the effects of happy eyeballs [RFC 6555] just got accepted last week. This uses a 3-years long ('13 - '16) dataset of TCP connect times towards ALEXA top 10K websites collected from 80 dual-stacked SamKnows probes. We just released [a] the paper. Thought to share it along: [a] http://goo.gl/JmKEax Feedback most welcome! You may recall preliminary versions of this work at RIPE 66 [b] and IETF 87 [c]. [b] https://ripe66.ripe.net/archives/video/1208 [c] https://vimeo.com/71407427 Abstract -------- The IETF has developed protocols that promote a healthy IPv4 and IPv6 co-existence. The Happy Eyeballs (HE) algorithm, for instance, prevents bad user experience in situations where IPv6 connectivity is broken. Using an active test (happy) that measures TCP connection establishment times, we evaluate the effects of the HE algorithm. The happy test measures against ALEXA top 10K websites from 80 SamKnows probes connected to dual-stacked networks representing 58 different ASes. Using a 3-years long (2013 - 2016) dataset, we show that TCP connect times to popular websites over IPv6 have considerably improved over time. As of May 2016, 18% of these websites are faster over IPv6 with 91% of the rest at most 1 ms slower. The historical trend shows that only around 1% of the TCP connect times over IPv6 were ever above the HE timer value (300 ms), which leaves around 2% chance for IPv4 to win a HE race towards these websites. As such, 99% of these websites prefer IPv6 connections more than 98% of the time. We show that although absolute TCP connect times (in ms) are not that far apart in both address families, HE with a 300 ms timer value tends to prefer slower IPv6 connections in around 90% of the cases. We show that lowering the HE timer value to 150 ms gives us a margin benefit of 10% while retaining same preference levels over IPv6.

Fwd: [Bp_ipv6] Starting IPv6 BPF 2016: Next call on 23rd June
by Michael Oghia 22 Jun '16

22 Jun '16

FYI. The IGF's Best Practice Forums provide tangible and useful outputs, and this year's IPv6 BPF aims to build on last year's momentum. I encourage anyone working with IPv6 to participate and spread this around your networks. Best, -Michael Oghia __________________ Independent #netgov consultant & editor 2015 ISOC IGF Ambassador Istanbul, Turkey Skype: mikeoghia Twitter <https://www.twitter.com/MikeOghia> *|* LinkedIn <https://www.linkedin.com/in/mikeoghia> ---------- Forwarded message ---------- From: Izumi Okutani <izumi(a)nic.ad.jp> Date: Tue, Jun 21, 2016 at 6:06 PM Subject: [Bp_ipv6] Starting IPv6 BPF 2016: Next call on 23rd June To: "bp_ipv6(a)intgovforum.org" <bp_ipv6(a)intgovforum.org> Dear Colleagues, We are starting work on IPv6 BPF 2016 and I am serving as a MAG Coordinator this year, with my colleague Sumon Ahmed Sabir. You can see our profiles at: http://www.intgovforum.org/cms/mag/45-mag-membership/3030-mag-2016-membersh… To start work for the BPF this year. we would like to invite you to: 1) Share your feedback on the attached Scope and Goals document for IPv6 BPF 2016 Close comments by: Fri 1st July 2) Join us in the call at UTC1600 Thu 23rd June *Register* < https://intgovforum.webex.com/intgovforum/j.php?RGID=ra8e66724ded8a366ee621… > After your request has been approved, you'll receive instructions for joining the meeting. To share some background, last year’s BPF on IPv6 focused on creating capacity building platforms and awareness raising, in the form of national and regional IPv6 taskforces and other initiatives. Building upon the conclusions of last year, the BPF on IPv6 organizers now suggest a focus on the economic decisions and commercial drivers behind the decision to adopt IPv6. Therefore, the target is non-technical people who can share economic/business perspectives. As we did last year, we would like to start with fixing the Scope and Goals document, to be the basis of our work for the output document to be produced as our BFP.

Hi all. Do anyone have isometric icon with IPv6 logo? We are creating animated form to order servers with IPv6. Now that looks like http://storage2.static.itmages.com/i/16/0621/h_1466530601_3472813_28e93c8b0… Thanks. Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Maximum acceptable IPv6 prefix in BGP table?
by Sergey 16 Jun '16

16 Jun '16

Hi, Looking at the BGP table I see stuff like this, not even /64: 2001:218:2000:5000::3a0/126 *[BGP/170] 2d 08:02:02, localpref 180 AS path: 12714 31133 3491 10026 I, validation-state: unverified > to 2a00:d18:fe03:fefe:a76d::1 via ae2.3386 As we can see this wasn't rejected by 3 AS-es. AFAIK, the minimum allocated space from RIRs is /48. Should we filter prefixes longer than this? -- Kind regards, CTO at *Foton Telecom CJSC (ru.fotontelecom)* Tel.: +7 (499) 679-99-99 AS42861 on PeeringDB <http://as42861.peeringdb.com/>, Qrator <https://radar.qrator.net/as42861>, BGP.HE.NET <http://bgp.he.net/AS42861> http://ipv6actnow.org/

Thanks, Colin. On my side, I'm not immediately keen to fill FIB slots with >/24 or >/48. But I'll keep an eye on what the rest of the community does and adjust accordingly if it makes sense. Mark.
