IPv6 brokenness in Norway, March 2010 (fwd)
by Tore Anderson 01 Apr '10

01 Apr '10

Hi, I've been posting these reports to the ipv6-ops list for some time now. Shane Kerr asked if I could post them here too, something which I don't mind doing at all, so here comes the one for March: -------- Opprinnelig melding -------- Emne: IPv6 brokenness in Norway, March 2010 Dato: Thu, 01 Apr 2010 01:35:01 +0200 Fra: Tore Anderson <tore.anderson(a)redpill-linpro.com> Organisasjon: Redpill Linpro AS Til: ipv6-ops(a)lists.cluenet.de Hi list, I'm happy to announce that the client loss is at an all-time low: 0.074% over the whole month, and it's been steadily decreasing. Buggy versions of Opera as well as Mac OS X appears to be responsible for about 95% of all measured client loss. Some noteworthy dates and events: 20100302: Opera 10.50 released, using getaddrinfo() on Windows. Gets an initial boost thanks to the Microsoft browser ballot. 20100322: Opera pushes 10.51 to their auto-update function. 20100324: A-Pressen Interaktiv re-joins the experiment. 20100327: First day of (extended) Easter holiday for many Norwegians. 20100331: The Gathering, a large data-party, kicks off. Provides native IPv6 connectivity to all participants. The numbers show that the release of Opera has helped quite a lot. Before the release of 10.50, the overall client loss was above 0.090%, but already right before Easter holiday it's below 0.065%. Easter holiday shows an interesting effect - both the measured amount of native IPv6 _and_ client loss drop sharply. The reason for this is that there's one particular network here in Norway that is the by far largest deployment of native IPv6 (about 80-85% of all requests over native IPv6 comes from it), but it is at the same time one of the largest causes of client loss, because it aggravates the Mac OS X/Opera problems significantly by filtering 6to4 traffic on ingress for a large number of end users (that have no native IPv6 service). The typical user on this network is also much more likely to take an extended Easter holiday than the the rest of Norway's population, I believe. I've been measuring the uptake of Opera 10.50+ on Windows Vista/7 in the whole period, and it has been steadily increasing even during the extended Easter holiday. About 72.5% of the Win Vista/7 Opera users were using 10.50+ at the end of the month. So while I do expect the client loss number to rebound somewhat when Easter holiday is over (on the 6th of April), I will be very surprised if it stabilises higher than 0.06-0.07%. The Mac OS X problem appears to occur when a client station has internet service using NAT/RFC 1918 numbering for IPv4, and 6to4 for IPv6. The Apple Airport Extreme SOHO router can operate in this way, and did so by default up until recently. In this case, OS X, or more precisely its getaddinfo() implementation, will prioritise 6to4 over IPv4. In addition, GNU libc (therefore all major Linux distributions) behave in the same way, but I'm not able to measure any impact, probably because there's so few Linux users to begin with. The issue is not actually a bug, but a shortcoming of RFC 3484. I've elaborated on it in reports to Apple and the glibc developers here: http://lists.apple.com/archives/Ipv6-dev/2010/Mar/msg00003.html http://sourceware.org/bugzilla/show_bug.cgi?id=11438 As an aside it's a bit fun to see how a relatively small deployment of IPv6 eyeballs like the data party (around 5000 participants I think) can dramatically change the amount of hits coming in from hosts with native IPv6. It more than doubled overnight. There's two reports attached, one generated from the readers of VG Multimedia - the online edition of Norways largest newspaper, and also Norway's largest web site, and the other from the readers of A-Pressen Interaktiv - an umbrella organisation that publishes the online editions of about 70 regional newspapers. When put together, they constitute Norway's fourth largest web site. In addition to the overall calculation, I've done five other calculations so you can see the individual impact of the different problems I've identified: - One that excludes hits from buggy versions of Opera on Windows Vista/7 (which auto-configures 6to4 and Teredo by default) excluded, - one that excludes hits from buggy versions of Opera on other versions of Windows (where a user must explicitly enable 6to4/Teredo), - one that excludes all hits from Mac OS X, - one that excludes all of the above, and - one that excludes all hits from the two significant end-user networks in Norway that filter 6to4 ingress traffic (one of them is the one I discussed above). This calculation does _not_ exclude Opera/OS X; when Opera and OS X are excluded, the two networks have about the same levels of client loss as rest of the internet. The seventh column shows approximately how much of the total client loss would have been avoided (in percentage points and percent), if the software in question didn't prefer 6to4 over IPv4, or, in the last case, if the two end-user networks mentioned didn't filter 6to4 on ingress.

ipv6 multicast
by Kristoff Bonne 01 Apr '10

01 Apr '10

Hi, As multicast is part of standard ipv6-stack, I was wondering how many ISPs who have ipv6 enabled have (or plan to have) ipv6 enabled on their backbone. Are there any statistics on this? Cheerio! Kr. Bonne.

IPv6 Pilot in NL: seeking customers
by Marco Hogewoning 30 Mar '10

30 Mar '10

(wearing my XS4ALL hat) We just announced to the media we are expanding our current trials to support native IPv6 over DSL to 1000 lines. These 1000 places are given away on a first come first serve basis. To give everybody a fair chance people can subscribe to this pilot starting Friday April 2nd, 12:00 CEST. In this pilot we ask for people to supply their own DSL cpe which is IPv6 capable or even hack around with linux images where possible. This pilot will serve 3 main goals: - Test interoperability between our gear and setup and the solitions currently on the market - Test those CPE solutions in the wild, we tested some of them in our own lab but it's hardly the same as everyday use in a random residential environement. - Fine tune our support procedures and figure out what training is needed. Next to that We'd love to see what problems will arise when IPv6 is switched on in a regular residential networking environment. Now obviously, since this is a DSL pilot there are some geographical boundaries on who can enter. If you happen to live in the Netherlands and are an XS4ALL customer please do subscribe. We already posted a list with some of the CPE we have tested and are known to work, these include some AVM FRITZ!Box models, some cisco SOHO boxes (8xx serie) and the latest release of Draytek Vigor. If you happen to know some others or happen to built DSL modems yourself, please contact me of list. Basic requirements are ADSL2+ with PPPoA, IPCP and IPv6CP using DHCPv6-PD to get the addresses. As a first result, the press release was picked up by a lot of media and the comments are mostly positive. Hopefully in a few weeks time we have some more data to report on. The original annoucement (in Dutch): http://www.xs4all.nl/klant/ipv6/ MarcoH

Internet Society IPv6 Workshop
by Phil Roberts 30 Mar '10

30 Mar '10

The Internet Society is hosting an IPv6 Deployment Day on April 22 in Seattle, Washington. The meeting is intended for operators who have deployed, are deploying, or are planning to deploy IPv6 in their networks. The proposed topics include business related issues for IPv6 deployment, discussion of pitfalls in IPv6 deployment, and specific technical issues due to IPv6 deployment that potentially affect the whole Internet. This is an open meeting and all are welcome, but space is limited so you will need to register: https://www.isoc.org/isoc/conferences/registration/?id=7ce20e4c88b7e328. If you have any questions please feel free to contact me, Phil Roberts (roberts(a)isoc.org), or Mat Ford (ford(a)isoc.org).

Measuring IPv6 at Web Clients and Caching Resolvers
by Mirjam Kuehne 25 Mar '10

25 Mar '10

[apologies for duplicates] Dear colleagues, As the remaining IPv4 space continues to shrink, it’s important to keep an eye on how the IPv6 Internet develops. We prototyped a method to measure the IPv6 capabilities of caching DNS resolvers that end-users use when browsing the web. The results of these measurements are now published on RIPE Labs: 1. A summary of the measurements and results can be found here: http://labs.ripe.net/content/measuring-ipv6-web-clients-and-caching-resolve… 2. Some more detailed analysis (including a breakdown of IPv6 usage per country and city) are here: http://labs.ripe.net/content/measuring-ipv6-web-clients-and-caching-resolve… 3. The methodology we use for these measurements are described here: http://labs.ripe.net/content/measuring-ipv6-web-clients-and-caching-resolve… All articles can be accessed from the RIPE Labs home page at http://labs.ripe.net If you have any comments or suggestions, please do not hesitate to submit them to the RIPE Labs forum or send them directly to me. Kind Regards, Mirjam Kuehne RIPE NCC

Call for agenda items for RIPE in Prague
by Shane Kerr 19 Mar '10

19 Mar '10

Hello all, The next RIPE meeting in Prague is coming up. We would like your input on the agenda for the meeting. We are hoping to have a brainstorming session at the beginning of the IPv6 working group, to try to come up with some ideas about how we can achieve the goals in our new charter. We would also like other items. Our intention is to look at each topic and try to get ones of interest to the larger RIPE community in the EOF portion of the meeting, and have the IPv6 working group focus on things interesting to people working in the IPv6 world. All items that are IPv6-related are of interest. Please send your proposals to David, Marco, or myself - all reasonable offers considered. Your friendly co-chair, -- Shane

IANA depletion in less than 1 year?
by Shane Kerr 17 Mar '10

17 Mar '10

Hey all, I noticed this site in someone's signature: http://ipv4depletion.com/ It uses a different prediction than the well-known one by Geoff Huston, although the results are not too different (which I guess is good): http://ipv4depletion.com/?page_id=4 Interesting. :) -- Shane
