v4 versus v6 -- who connects faster?
by Bajpai, Vaibhav 23 May '16

23 May '16

Dear v6 WG, Here [a] is a toy v6 service I came up with during the RIPE Atlas hackathon over this weekend. Thought I share this along: [a] http://goo.gl/hbzbwD You enter a dual-stacked website (ALEXA top 10K) and it shows you the difference in TCP connect times over v4 and v6 as seen by all dual-stacked RIPE Atlas probes (~1.3K probes). You can also filter the visualisation from a specific origin-AS. This additional filter can be useful to view performance towards a website from a specific origin-AS (say 3320). Disclaimer: This is an outcome of a 1.5d long hackathon project. As such, the codebase is possibly inundated with bugs. Please don’t see it as a production service :-) Best, Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com<http://www.vaibhavbajpai.com> Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany ===================================

Hello Vaibhav, The map with blue/red is really a nice one :-) May I dare to propose some improvements? * on the blue/red map, be sure to have blue meaning all the time that IPv6 is faster (the legend is unclear and by using those tools, I know that this is not trivial to do) * State the date of the 'scan' * Some web sites are in the top 10K of Alexa but are not in: www.iet.org, www.lesoir.be, .... (Even www.ripe.net is not in the data :-) but RIPE is only 25.000th so out of your data set) Again, nice visualisation! -éric From: ipv6-wg <ipv6-wg-bounces(a)ripe.net<mailto:ipv6-wg-bounces@ripe.net>> on behalf of "Bajpai, Vaibhav" <v.bajpai(a)jacobs-university.de<mailto:v.bajpai@jacobs-university.de>> Date: Monday 23 May 2016 at 08:08 To: "ipv6-wg(a)ripe.net<mailto:ipv6-wg@ripe.net> IPv6" <ipv6-wg(a)ripe.net<mailto:ipv6-wg@ripe.net>> Subject: [ipv6-wg] v4 versus v6 -- who connects faster?

IPv6 residential deployment survey (looking into technical aspects)
by JORDI PALET MARTINEZ 20 May '16

20 May '16

Hi all, I got so much input for a small “email survey”, that I’ve decided to make it more complete and on-line. The results will be published and updated every month or so, I will provide ASAP the link to those stats. No personal data will be published. http://survey.consulintel.es/index.php/175122 (If you know your network, it takes less than 2 minutes to complete it) It can be responded even if is not yet a commercial service, and customers can also respond, not just the ISP. However, to avoid duplicate data, make sure to include the country and ISP name. For those that already replied to me by email, it will be much better if you can fill in the on-line survey. Otherwise, after a week or so, I will input “manually” the data that you provided, but then there will be many “empty” questions. Please, feel free to circulate this message as much as you can ! Thanks a lot!

IPv6 residential service: What prefix, static, dynamic, extra cost ?
by JORDI PALET MARTINEZ 19 May '16

19 May '16

Hi all, I’m trying to make a table to compare the way actual IPv6 services to residential customers are being provissioned mainly in EU, but I will do to the same also in other regions. I’m happy to make a single “table” with all the information that I can collect and publish it so others can make use of it, and keep it updated, may be in some URL, etc. So here are the questions for actual IPv6 services providers to residential customers: 1) What prefix size is provided? 2) Is that prefix static or dynamic? 3) In case is dynamic, there is a chance for static? 4) Any extra cost for having it static, or having a bigger prefix (i.e., /48 instead of /56)? 5) If the customer has already a static IPv4 with a monthly charge, is still IPv6 static prefix being charged on top of that? Please state the ISP name, country and if you have a URL or document that state this service, other options, etc. If you’re not yet providing the service, but it will happen soon and the “model” for this has been already defined, please let me know as well! Hopefully I can get a lot of anwers! Private or in the list, I’m fine either way. Thanks! Regards, Jordi PD: In my opinion it should be /48 by default, static and opt-in to dynamic, no extra charge on top of the Internet service price, but I know many ISPs will not agree :-( Here just trying to collect the info in a single place. ********************************************** IPv4 is over Are you ready for the new Internet ? http://www.consulintel.es The IPv6 Company This electronic message contains information which may be privileged or confidential.

Re: [ipv6-wg] IPv6 cloud!

Hi Ole and list, "Ole Troan (otroan)" <otroan(a)cisco.com> writes: >> Considering the increasing reports of people having problems with >> DS-Lite > > Any more details on that? > New problems not mentioned in RFC6269? sorry I haven't got the time right now to review RFC6269 for what's exactly mentioned there and what isn't, but: When I do IPv6 trainings these days it's about one in eight who is struggling with their land line access, which is based on DS-Lite and which reasonably well matches the estimated percentage of DS-Lite on land lines. The problems are however of a somewhat different nature than what RFC6269 addresses; they are roughly these: - Various services don't work. Like STUN, and due to that, SIP. And apparently various VPN solutions, too, but I never got access to any details with this. The real culprit here seems to be restricted cone NAT in the AFTR, plus apparently IPsec not working through DS-Lite. - There have been multiple reports that during peak hours there are significant connection drops. The impact varies from user to user as well as from ISP to ISP, apparently. Or as one user put it: "I solved the problem. I just don't even try to access IPv4-only web pages on saturday afternoons any longer." I don't have access to the AFTRs involved, so I can't reliably tell what's happening there, but from the descriptions I got it looks like some of them are actually running out of memory/CAM during peak hours and start to drop the connections. This is economically plausible, too, since the ISPs won't spend significant money on AFTR hardware until problems have already shown up. - First level support is frequently completely helpless when confronted with DS-Lite, or even IPv6 in general. The most annoying aspect here is that frequently it comes across that "it's a problem with IPv6" and "if you keep complaining they'll switch it off again for you" (i.e. they go back to IPv4-only connectivity without restricted cone NAT). All the information I have here is largely based on anecdotal reports, but enough of them for me to consider these problems anything but isolated cases.

Re: [ipv6-wg] ipv6-wg Digest, Vol 55, Issue 4 -NAT64 Benedikt Stockebrand
by Thorsten Trottier 05 May '16

05 May '16

Hello Benedikt, I’m not a friend of NAT as well, but demonize NAT for any actions is a kind of overdo, isn’t it. We are living with NAT a long time now for better or for worse. A customer of mine (enterprise customer with hundreds of sites and thousands of employees) has setup his IPv6 project more than 4 years ago and plans to be finished 2020. Their project team produced hundreds of pages in planning strategy, timeline and migration. In one of their sub projects they saw NAT as a interim solution for their Webservice as best method. We implemented a redundant NAT64 solution based on Cisco Adress Family Translation. Now IPv6-only or Dual-stacked Users can hit the customers web service which is still IPv4 only. Of course not a low-cost solution, but for „political" and/or technical reasons a solid way.

what is v6-only?
by Bajpai, Vaibhav 05 May '16

05 May '16

Hello, What does v6-only mean? a) A client only has v6 address and can only route to v6 destinations b) A client only has v6 address but can route to dual-stack destinations using a network translator (such as NAT64) IIRC, IETF SSIDs are named: 'v6 only + nat64’. Personally when someone says v6-only I presume a), but lately I have seen people say v6-only although they mean b).

20 Apr '16

Dear IPv6 Enthusiasts ;) I know that 23 of May 2016 when RIPE72 will start looks so away but we (IPv6 WG Chairs) like to plan ahead! If you would like to present at IPv6 WG session or just have any suggestions on the agenda (what we should or should not be talking about) - please email ipv6-wg-chairs(a)ripe.net >From presenters we need the following information: - a tentative title of your talk; - short summary - how much time you need (I'd recommend allowing 5 mins for questions). For the last few meetings we filled all the agenda slots quite earlier and unfortunately had to reject a number of interesting talks because they were submitted too late. So don't be shy! If you *might* be able to present but not sure yet - also let us know. -- SY, Jen Linkova aka Furry on behalf of IPv6 WG Chairs.

29 Feb '16

Dear colleagues, This week, we saw the 10,000th Local Internet Registry (LIR) received IPv6 addresses. The first block of IPv6 addresses was allocated from IANA to the RIPE NCC in 1999, so we have been distributing IPv6 addresses for 17 years. In this new article on RIPE Labs we track the policy developments that have made it progressively easier for LIRs to get the IPv6 they need: https://labs.ripe.net/Members/nathalie_nathalie/10-000-lirs-with-ipv6-resou… Kind regards, Mirjam Kuehne RIPE NCC

Users turning off IPv6 because of YouTube
by Ondřej Caletka 14 Jan '16

14 Jan '16

Hello list, I've came across a new reason people are turning off IPv6 on their computers. Looks like GeoIP restrictions of YouTube are somehow broken making some videos playable over IPv4 but 'not accessible from your country' over IPv6. For example this music video: https://www.youtube.com/watch?v=44XYEeD1A1U is perfectly playable from addresses: 147.32.0.0/16 and 195.113.0.0/16 but not playable from 2001:718::/32 The network is deployed as native dualstack and both address families are correctly registered in the RIPE database to Prague. I guess there's probably nothing we can do from the network operator's point of view. Anyone experiencing the same? Cheers, Ondřej Caletka CESNET

IGF 2015 output document: "Creating an Enabling Environment for IPv6 Adoption"
by Marco Hogewoning 09 Dec '15

09 Dec '15

Dear colleagues, In earlier emails we asked you to review the draft outcome document for the Internet Governance Forum (IGF) Best Practice Forum on IPv6. This is to let you know the 2015 IGF inter-sessional work has now concluded and the final output document has been published on the IGF website. It is available for download at: http://goo.gl/BXBzTn Acknowledging the need for a increased rate of IPv6 adoption, the documents highlights numerous examples and best practices that can help businesses and governments with their IPv6 deployment projects. A large section of the document is dedicated to role and function of IPv6 task forces, which can be instrumental to a successful IPv6 deployment in a particular country or region. In addition it provides an overview of various capacity building programs that are available, which includes the RIPE NCC Training Courses and IPv6 Roadshows. We hope this document provides useful guidance for our community members and stakeholders that face the important step of enabling IPv6 in their networks and services. We would like to thank everybody who contributed to this document and in particular Susan Chalmers, Izumi Okutani and Wim Degezelle who jointly coordinated and supported the work on behalf of the IGF Multistakeholder Advisory Group (MAG).

first "smart" food processor with IPv6
by JORDI PALET MARTINEZ 01 Dec '15

01 Dec '15

(I hope you don’t kill me if you believe is off-topic, but I couldn’t resist) I guess this is interesting for this list (I’m not associated with the vendor) and may be a good Xmas present … if you enjoy cooking as I do ! http://www.mycook.es/mycook-touch-smart-cooking/ This food processor uses Android and is IPv6 enabled with a touch screen and WiFi connectivity. Seems to be able to do the shopping list (and actually shopping when associated shops finish their apps) for the recipes, share recipes among different users and devices, upgradable over WiFi (for firmware and recipes, of course), diet generator, news, promotions, suggestions, etc., etc. I’m testing it in the next few days ;-) I always use a Thermomix (actually use it a lot as I love cooking), and the price is about the same, 990 Euros + VAT, so the Mycook Touch it is not expensive compared with competitors (which are not “smart” neither WiFi enabled). Taurus is a well known Spanish vendor, and I think is available also in many other countries (http://taurus-home.com/en). Note: The link is only for the Spanish version, if you click on English (right now), it brings you to the older model which is not IP enabled at all.

ripemtg-nat64 network at RIPE71: complain here ;)
by Jen Linkova 19 Nov '15

19 Nov '15

Hi guys, As you might have noticed there is a NAT64 SSID. This thread is for complains about that network. Please use ripemtg-nat64 SSID. Please let us know if smth goes wrong. if you have network issues while using that SSID and switching to dual-stack one fixes the problem - please reply to this thread (indeed you can create a new one, I was just thinking that keeping everything in one thread might make our life easier but I might be wrong...). -- SY, Jen Linkova aka Furry

New on RIPE Labs: Lost Stars: Why Operators Switch off IPv6
by Mirjam Kuehne 18 Nov '15

18 Nov '15

Dear colleagues, One of the measurements that we have been running for a long time is IPv6 RIPEness, where we measure the IPv6 activity of the RIPE NCC members. We award members with stars if they (for example) announce their IPv6 allocation in the global routing table. We discovered that 460 RIPE NCC members had recently stopped announcing their IPv6 prefix and asked them why. Please find the results on RIPE Labs: https://labs.ripe.net/Members/nathalie_nathalie/lost-stars-why-operators-sw… Nathalie Trenaman will present this in the IPv6 working group at RIPE 71. Kind regards, Mirjam Kuehne RIPE NCC

IPv6-only network during RIPE 71
by Ondřej Caletka 10 Nov '15

10 Nov '15

Dear WG, as the RIPE 71 approaches, I would like to revive discussion about the IPv6-only network during meeting, that has been kindly provided since RIPE 67. I think the technology is mature enough to be provided as a regular RIPE NCC service during the meeting - that means regular network name and, most important, a password that is propagated in the same way the normal Wi-Fi network password is. This is especially important for the one third of newcomers that have had a big troubles learning the password of the IPV6ONLYEXP network. After RIPE 70, I proposed a "drastic" approach [1], renaming the dual-stack meeting network to -legacy and promote the NAT64 network as the default. This is the same way they do it on FOSDEM since 2014 [2]. But maybe we could try a slow start first, keeping the dual-stacked network the default and offering the NAT64 network with some suffix like -v6only. Any ideas? -- Ondřej Caletka CESNET [1]: https://www.ripe.net/ripe/mail/archives/ipv6-wg/2015-May/002632.html [2]: https://archive.fosdem.org/2015/news/2015-01-31-ipv6-only-again/
