6to4 and teredo pingables?
by Aleksi Suhonen 13 May '12

13 May '12

Hi, We run 6to4 and Teredo relay routers and in order to monitor the service our network monitoring system has been pinging a handful of 6to4 and Teredo addresses elsewhere. If more than one of those addresses fail to answer pings, an alarm is raised. Now I'm looking for a few more addresses I could ping, so I could raise the alert threshold a bit. Any volunteers? And in case anyone else wants to ping some of our hosts, here's a couple of candidates: (sorry, no Teredo hosts) ns.trex.fi. IN AAAA 2002:c38c:c38c:15::35 mail.trex.fi. IN AAAA 2002:c38c:c38c:14:203:baff:fe0f:d68b Yours sincerely, -- Aleksi Suhonen / TREX

[apologies for duplicate mails] Dear colleagues, You can now use RIPE Atlas to test your IPv6 reachability. This also works if you do not host a RIPE Atlas probe yourself. However, please note that this is only available to RIPE NCC members. Please find the details on RIPE Labs: https://labs.ripe.net/Members/becha/test-your-ipv6-reachability-using-ripe-… If you have any comments or questions, please let us know.

IETF I-D: Security Implications of IPv6 on IPv4 Networks
by Fernando Gont 02 May '12

02 May '12

Folks, A couple of weeks ago we published a new IETF I-D entitled "Security Implications of IPv6 on IPv4 networks". The I-D is available at: <http://tools.ietf.org/html/draft-gont-opsec-ipv6-implications-on-ipv4-nets> The Abstract of the I-D is: ---- cut here ---- This document discusses the security implications of native IPv6 support and IPv6 transition/co-existence technologies on "IPv4-only" networks, and describes possible mitigations for the aforementioned issues. ---- cut here ---- We're currently working on a revision of the document, so any comments will be really appreciated. Thanks! Best regards, -- Fernando Gont SI6 Networks e-mail: fgont(a)si6networks.com PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492

New on RIPE Labs: Update on IPv6 Address Distribution
by Mirjam Kuehne 02 May '12

02 May '12

Dear colleagues, At the recent RIPE Meeting we presented some IPv6 address distribution statistics. In this RIPE Labs article, you can find statistics on IPv6 allocations and assignments. In particular, the article details what affect the removal of the requirement to be multihomed had on the number of assignments and the relationship between the age of an LIR and the number of IPv6 addresses they have received. https://labs.ripe.net/Members/mirjam/update-on-ipv6-address-distribution Kind regards, Mirjam Kuehne RIPE NCC

Last Call for publication of RIPE-501bis (reply by 20120426)
by David Kessens 02 May '12

02 May '12

In the IPv6 working session at the RIPE meeting in Slovenia, we discussed: http://go6.si/docs/Requirements-for-IPv6-in-ICT-equipment-v.9.pdf The meeting participants felt that the document is now ready for publication. Therefore, I would like to give everybody a final chance to bring up major issues that must be resolved before publication. Please comment by Thu 20120426 if you have major issues that require a delay in publication. We will ask the RIPE NCC to publish the document after the Last Call ends if no serious issues are uncovered by that date. The RIPE NCC will do an editorial pass for spelling, grammar and minor issues before it will publish the document. Feel free to contact the working group chairs directly <ipv6-wg-chairs(a)ripe.net> if you find anything minor that doesn't need working group review and we will make sure that it gets fixed in the final document. Thanks, David, Shane & Marco ---

Fw: WG Review: sunset4 (sunset4)
by Shane Kerr 18 Apr '12

18 Apr '12

All, FYI, the IETF may be starting some (more) work of interest to IPv6 folks. Perhaps this will inspire us to change the IPv6 working group to the IPv4 CGN/NAT working group. ;) Cheers, -- Shane Begin forwarded message: Date: Tue, 17 Apr 2012 09:41:57 -0700 From: IESG Secretary <iesg-secretary(a)ietf.org> To: IETF Announcement List <ietf-announce(a)ietf.org> Subject: WG Review: sunset4 (sunset4) A new IETF working group has been proposed in the Internet Area. The IESG has not made any determination as yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg(a)ietf.org) by Tuesday, April 24, 2012. sunset4 (sunset4) ----------------------------------------- Status: Proposed Working Group Last Updated: 2012-04-13 Chairs: TBD Internet Area Directors: Ralph Droms <rdroms.ietf(a)gmail.com> Brian Haberman <brian(a)innovationslab.net> <TBD> Internet Area Advisor: <TBD> Area Advisors: OPS: <TBD> TSV: <TBD> RTG: <TBD> Mailing Lists: <TBD, pending final WG name> Description of Working Group: The IETF is committed to the deployment of IPv6 to ensure the evolution of the Internet. However, the IPv4-only components of the Internet must continue to operate as much as possible during the transition from IPv4 to IPv6. The Working Group will standardize technologies that facilitate the graceful sunsetting of the IPv4 Internet in the context of the exhaustion of IPv4 address space while IPv6 is deployed. These technologies will likely be less optimal than equivalent technologies for IPv6-only and dual-stack networks. The Working Group works only on IPv4 protocols to facilitate IPv4 sunsetting. The Working Group may work on fixing security bugs in existing IPv4-specific protocols but is not chartered to add new security functionality to those protocols. The working group will provide a single venue for the consideration of IPv4 sunsetting, while ensuring that any such technologies do not impede the deployment of IPv6 and do not duplicate functions and capabilities already available in existing technologies. Therefore, along the lines of draft-george-ipv6-support, before the working group adopts any technology, it must: 1) describe the problem to be solved and show that there is widespread demand for a solution 2) demonstrate that the problem can not be solved with existing technologies 3) provide a description of the proposed solution along with the impact on current IPv4-only use and its ability to promote the deployment of IPv6 These steps will likely be described in the form of a use case and requirements document. Only after the above mentioned steps have been completed and the results accepted by the community will the IETF consider adding new work items to the Working Group charter. This new work may include protocol specifications. The work spans over multiple IETF areas including as Internet, Operations, Transport and Routing. Therefore, cross-area coordination and support is essential and required. Any work on IPv4 to IPv6 transition methods is out of scope. The initial work items are: * Review current CGN documents, including requirements for standardization, and determine is CGN is a suitable sunsetting technology to become a work item * Gap analysis of IPv4 features to facilitate IPv4 sunsetting Milestones 2012-09 Complete review of CGN and, if necessary, propose CGN work items 2013-06 Send gap analysis on IPv4 sunsetting to IESG

by Jan Zorz ＠ go6.si 11 Apr '12

11 Apr '12

Dear @IPv6 WG Long time promised Slo IPv6 study, done for our government in 2010 is now available in English language. The authors did a revision and added few changes just in order to make document more "current". All in all, many things that we wrote is 2010 still holds. You can download the PDF from following page: http://go6.si/en/2012/04/slovenian-ipv6-study-english-version/ In the doc there are 11 key questions from governmental point of view and many answers to them. Hope that this work can help some governments in their way towards IPv6. See you all in few days, Jan Zorz Go6 Institute.

Preview of the final RIPE-501bis.
by Jan Zorz ＠ go6.si 10 Apr '12

10 Apr '12

Dear IPv6 WG. After long and exhausting IETF week, where we met with some great experts from the industry and did some sanity checks and corrected some mistakes and misunderstandings in the RIPE-501-replacement document, we are issuing next (9th) version of the draft, that is in our opinion really final one. I mean it. Last one. There was lot's of time, efforts and work put into this document and I think we are done. This replacement document is also meant as a some kind of input or initial template for EU IPv6 profile, so we wanted it to be very solid and accurate. Thanks to all of you involved, you know who you are (you are all in Acknowledgements section ;) ) and thnx to this WG and their co-chairs for support, help and all good comments. We already set the last version to RIPE-NCC for grammar checks and conversion into HTML in order to appear in RIPE Documents section as a draft, but meantime, we are publishing the last version also in PDF in order for you, community, to read it prior to RIPE64 meeting. http://go6.si/docs/Requirements-for-IPv6-in-ICT-equipment-v.9.pdf Please, those of you who are interested and have time, read it and express you r opinions and possible comments. Rumor has it, that we'll have "review" period over the RIPE64 meeting and Last call shortly after that. As this is not an official PDP, we can also propose chairs to change the procedure, if there is any need for that. Track of the progress and different versions of the draft can be found at: http://go6.si/ripe501bis/ Cheers from co-authors: Merike, Sander and Jan
