Last Call: Confirmation of co-chairs (20100217)
by David Kessens 10 Feb '10

10 Feb '10

The discussion phase regarding new co-chair positions has now ended. It seems that there is strong support to appoint: Shane Kerr http://www.ripe.net/ripe/maillists/archives/ipv6-wg/2010/msg00038.html Marco Hogewoning http://www.ripe.net/ripe/maillists/archives/ipv6-wg/2010/msg00041.html as additional co-chairs for the ipv6 working group. Please let us know if you have objections to such a solution by the end of Wed Feb 17, 2010 in a time zone of your choice. There is no need to restate your supportive position again as there was already a significant number of people that expressed support for this approach. Thanks, David Kessens ---

announcing DNS64-NAT64 opensource implementations
by Marc Blanchet 08 Feb '10

08 Feb '10

<sorry for cross-posting/> This is to announce the availability of two NAT64-DNS64 open-source implementations by Viagenie, as follows: ====== NAT64 ====== BSD PF: this implementation of NAT64 is made by modifying the PF packet filter available on BSD systems. A new 'nat64' statement is created in the pf.conf file to enable the nat64 functionality. Linux Netfilter: The implementation of NAT64 for linux is available as a kernel module. It uses Netfilter's facilities for packet interception. The configuration is done with parameters provided at module insertion. ====== DNS64 ====== As announced in july 2009 during IETF Stockholm, the companion DNS64 functionality is also available in two implementations, as follows: BIND: this implementation of DNS64 is made by modifying the BIND DNS server. A new "dns64-prefix" statement in options is created in the named.conf file to enable DNS64 functionality. Unbound: this implementation of DNS64 is made by adding a module to the Unbound DNS server. To enable the DNS64 functionality, the module should be declared and the dns64-prefix statement should be added in the unbound.conf file. The two functionalities (NAT64 and DNS64) make a complete system for translating IPv6-IPv4 packets. The source code, some pre-compiled packages and project description are available at: http://ecdysis.viagenie.ca. This project was funded by NLNet foundation and Viagenie. We are looking for feedback, patches, suggestions from the community. http://ecdysis.viagenie.ca Regards, Marc Blanchet, Simon Perreault, Jean-Philippe Dionne Viagenie

IPv6 experiments at future RIPE Meetings
by James Aldridge 08 Feb '10

08 Feb '10

Reading the minutes of the IPv6 WG at RIPE 59 I read: > David asked the audience if the IPv6 Hour should be rerun at future > meetings.. There is consensus that it should be. Rob Blokzijl has asked that we treat the RIPE Meeting network as a production network. This effectively means that we won't be turning off the dual-stack network for another "IPv6 Hour". What we can do is to build the IPv6 only networks as we did in Berlin and make these available to anyone who wants to use them, but without the complications caused by the IPv6 Hour. One question that remains is whether, with rfc2766 now "historic", providing NAT-PT on the IPv6-only networks is worthwhile for RIPE 60 and future meetings. Would it be enough just to provide the IPv6 networks but without any translation to be able to reach the IPv4 legacy Internet? Any feedback would be appreciated. Regards, James -- James Aldridge, Senior Systems & Network Engineer, RIPE NCC RIPE Meeting technical team

Re: RFC 1918 in "production networks"

Try it. > Given the number of attendees, the chances for address collisions with > at least one participant's home network can be assumed to be near 100%. One workaround would be to have two (vastly different) 1918 prefixes and giving people the possibility to switch (so, 2 SSID's, 2 prefixes, say 192.168.224.0/20 and 10.210.32.0/20). Chances that someone will conflict with both, are small. For better or worse, we will need to learn how to deal with this - denying these issues doesn't fix the fact that these situations will happen, without the escape of availability of public IPv4 addresses, in the near future. And, of course, if nobody puts pressure on the VPN-sellers, these issues will stick around for *years*. Geert Jan

IPv6 Act Now update
by Chris Buckridge 04 Feb '10

04 Feb '10

Hi all, A couple of items from the IPv6 Act Now newsfeed over the last week that may be of interest: YouTube Turns On IPv6 support, Net Traffic Spikes (2 Feb 2010) Martin Millnert has already posted some useful information to the list on this subject. Google has quietly turned on IPv6 support for its YouTube video streaming Web site, which sent a spike of IPv6 traffic across the Internet. <http://www.ipv6actnow.org/2010/02/youtube-turns-on-ipv6-support-net-traffic… > IPv6: the new platform (3 Feb 2010) Some perspectives on IPv6 deployment from India, the second largest telecom market in the world. The article includes discussion of the IPv6 survey done in the Asia Pacific recently by TNO/GNKS, who worked with the European Commission and the RIPE NCC on an IPv6 Deployment Monitoring Survey last year: <http://www.ipv6actnow.org/2010/02/ipv6-the-new-platform/> Separate to IPv6 Act Now, the IPv6 adoption issue continues to gain exposure in the mainstream press. Dutch news site nu.nl ran an article this week based on the recent announcement from the NRO and ICANN that the pool of available IPv4 address space has reached 10%: <http://www.nu.nl/internet/2175537/internetadressen-raken.html> [in Dutch] Regards, Chris Buckridge, RIPE NCC

How polluted is 1/8?
by Mirjam Kuehne 03 Feb '10

03 Feb '10

[Apologies for duplicates] Dear colleagues, After 1/8 was allocated to APNIC last week, the RIPE NCC did some measurements to find out how "polluted" this block really is. See some surprising results on RIPE Labs: http://labs.ripe.net/content/pollution-18 Please also note the call for feedback at the bottom of the article. Kind Regards, Mirjam Kuehne

Youtube over IPv6!
by Martin Millnert 03 Feb '10

03 Feb '10

Hello fellow IPv6 admirers, (I'm sending this here on behalf of Shane. :) ) As you might know already, Google has been so *tremendously* kind to, as of ~22 hours ago, initiate the enabling of their Youtube site over IPv6. It is currently available to participants in their Google over IPv6 program, http://www.google.com/intl/en/ipv6/ . The www.youtube.com user interface so far does *not* have any AAAA published, but the *much* more important (traffic wise) image and video servers do. Use tcpdump to verify. Eg., anticimex@hsa:~$ host s.ytimg.com s.ytimg.com is an alias for static.cache.l.google.com. static.cache.l.google.com has address 74.125.13.213 static.cache.l.google.com has IPv6 address 2001:4860:4001:402::15 anticimex@hsa:~$ host v1.lscache1.c.youtube.com v1.lscache1.c.youtube.com is an alias for v1.lscache1.l.google.com. v1.lscache1.l.google.com has address 74.125.97.80 v1.lscache1.l.google.com has IPv6 address 2001:4860:4001:402::10 The time when it began is clearly visible in our own IPv6 graphs, http://stats.csbnet.se/public/ipv6/csbnet-ipv6-traffictypes.html , and you can see similar correlated data at for example http://www.de-cix.net/content/network.html . To figure out all the mappings they give you, if you want to trace etc, something similar to: "for i in `seq 1 24 `; do for y in `seq 1 8 `; do host v$i.lscache$y.c.youtube.com ; done ; done | grep 'IPv6 address' | cut -d' ' -f 1,5 | sort -uk2" could be used - at least from where I sit. Adjust for correctness. I'm sure that as this matures and bugs are wiped out, there will no longer be any need for the Google over IPv6 program and everybody will be able to access this. Until then, join! :) I bow to the Google IPv6 team, their netops and everybody there that is working so hard to give the Internet true CONTENT on IPv6. Yippie! From 48514, much of love! Thank you guys (and gals)! Regards, -- Martin Millnert <millnert(a)csbnet.se>
