v6 World Connectivity To v4 World
by Matthew Walster 14 Jan '12

14 Jan '12

Apologies if this would be more suitable for IETF v6ops rather than IPv6-WG, I'm not overly familiar with the v6 development community. As is painfully apparent, most of the world if v4 only at the moment - and the various DNS ALGs etc for getting v4 connectivity onto v6 only connections seem "hackish" at best, and have real problems when it comes to things such as 1500-byte v4 packets needing fragmenting to travel over v6 nets. While playing with my local ssh daemon, I was reminded that inside my ssh client is a SOCKS5 server - I can connect to it by just setting my global SOCKS setting to use the localhost and all the traffic is forwarded down the tunnel to the remote host for processing. I was wondering whether anyone had any experience in setting a SOCKS proxy on a v6-only host, where the DNS/SOCKS proxies have both v4 and v6 addressing, and whether they can then access v4 services like web sites, mail servers, gaming applications etc. The basic idea is that you would use the v6 internet where possible, and go through your ISPs v4 SOCKS gateway for anything that didn't return a AAAA record. Is that idea right, and if so, is it sustainable? Assuming for the moment that I've made a correct assumption, is there a way we can make the process easier? Back in v4 world, there's DHCP option 252 which allows you to configure a WPAD file that would be downloaded and parsed by your web browser, setting HTTP proxies etc for certain classes of service - non-local traffic etc. Is it feasible to add an option to DHCPv6 so that a "v4 compatibility" string could be set, whereby a fall-back SOCKS server is used for non-v6 connections? Thinking off the top of my head, it would work as follows for the "no-clue" home user: User's router talks to ISP via DHCPv6: gets response detailing address to use also gets prefix delegation for local LAN usage also gets v4 compatibility string, which it stores for relaying to clients User's router listens for DHCPv6 requests, issues clients on local LAN public v6 addresses: sets option for v4-compatibility for clients User's computer turns on, asks for addressing information: gets v6 address via DHCPv6 gets v4-compatibility string and sets global SOCKS proxy variable, if not manually configured gets other string - DNS servers, routes etc. I stress that this idea is for v6/v4 co-existence, and isn't designed for "islands of v4" or "islands of v6", it would of course assume that v4 availability is restricted and a real effort to move to v6 was made. It's a transition mechanism that should be easy to turn off once most of the services have been migrated (hopefully transparently to the end customer). If there is a major flaw in my idea, I'd greatly appreciate constructive criticism and feedback! Matthew Walster

Latest 6::gle phone Nexus supports IPv6 on 3G
by Jan Zorz ＠ go6.si 02 Jan '12

02 Jan '12

All good in new year, the year of IPv6 :) In Go6Lab we tested new 6::gle phone with Android 4 and good news is, that it supports IPv6 PDP context over 3G. With Cameron from T-Mobile USA we are compiling list of apps, that are not working in IPv6-only environment, but for now we can live with it in everyday life :) The list will be published and compiled later. Short first report with snapshots: http://go6.si/en/2011/12/samsung-galaxy-nexus-nov-google-phone-podpira-tudi… Good news for start of new year. Cheers, Jan Zorz Go6 Institute Slovenia, CEO

Update in the RIPE document for IPv6 Allocation and Assignment policies
by Emilio Madaio 07 Dec '11

07 Dec '11

Dear colleagues, An editorial correction has been made to ripe-523 "IPv6 Address Allocation and Assignment Policy". The updated document has been renumbered to ripe-538. It is available at: http://www.ripe.net/ripe/docs/ripe-538 There was a mismatch between the policy text and the index title for section 5.4.2. This mismatch occurred between the updates from ripe-421 to ripe-450. Apologies for any inconvenience caused. Kind regards, Emilio Madaio Policy Development Officer RIPE NCC

on RIPE-523 IPv6 Address Allocation and Assignment Policy
by Jac Kloots 05 Dec '11

05 Dec '11

While I was reading RIPE-523 I noticed a mismatch between titles in the indexand the paragraph itself. The index for 5.4.2 says: Assignments shorter than a /48 to a single End Site While the paragraph title is: Assignment of multiple /48s to a single End Site Any change on getting this in line? Regards, Jac -- Jac Kloots Network Services SURFnet bv

Last call on the replacement of ripe-501 "Requirements for IPv6 in ICT equipment"
by Marco Hogewoning 15 Nov '11

15 Nov '11

Dear colleagues, Following up on feedback received from the community during and after the publication of the ripe-501. The authors have worked on a replacement document, incorporating suggestions made by the community and clarifying some of the requirements. Prior draft versions of this document have been posted to this mailing list in the past months. The resulting final draft document is now published on the website and reachable via https://www.ripe.net/ripe/docs/other-documents/requirements-for-ipv6-in-ict… We would like the community to review this document. Although this is not a formal policy proposal, we would like to issue a 4 week working group last call on this draft before publication. Minor changes like typos or formatting can be sent to the authors or to me directly. Please raise any questions or comments on the content to this list. Unless blocking issues are found on this text, it is our intent to publish this draft as a RIPE Document and to change the status of the current document ripe-501 to obsolete, with a reference to the new document. The authors will also present on this draft during the IPv6 working group session at the Vienna meeting. Please send any comments before Thursday November 10 2011, which is 4 weeks from now. Regards, Marco Hogewoning on behalf of the IPv6 Working Group chairs
