96 more bits... time for some magic after all?
by Shane Kerr 26 Oct '13

26 Oct '13

All, We saw two presentations by network architects at the RIPE meeting that used bits in their IPv6 addressing plan to carry meaning beyond simple network topology and packet routing. For example, declaring a specific bit in the address to be 1 for voice traffic or 0 otherwise. There are motivations for doing this, which may or may not be valid in any particular case. There are ways to lessen the amount of addresses consumed by this (for example by assigning /56 instead of /48 to end users). But I think that the important thing is that we have historically not considered this sort of use with address allocation policy. In face, RFC 2050bis was *just* published as RFC 7050: Cheers, -- Shane

Request for feedback on IETF I-D draft-v6ops-vyncke-balanced-ipv6-security
by Anfinsen, Ragnar 22 Oct '13

22 Oct '13

Dear all, The authors would like to invite the community to review and comment on IETF I-D draft-v6ops-vyncke-balanced-ipv6-security. <snip> Abstract This document describes how an IPv6 residential Customer Premise Equipment (CPE) can have a balanced security policy that allows for a mostly end-to-end connectivity while keeping the major threats outside of the home. It is based on an actual IPv6 deployment by Swisscom and proposes to allow all packets inbound/outbound EXCEPT for some layer-4 ports where attacks and vulnerabilities (such as weak passwords) are well-known. </snip> http://tools.ietf.org/html/draft-v6ops-vyncke-balanced-ipv6-security We have received feedback from the IETF community that there should not be any explicit list of ports to be blocked in the document. The authors feels that this list should be maintained by a neutral internet body, however we need suggestions from the community on who this could be solved. So basically there are a few options on who the list could be managed; * Let the ISP/Vendor define and maintain the list by them selves. * Let the community maintain such list using consensus. * Ask a neutral internet body (insert favorite here) to manage the list based on the actual threat picture. Please keep in mind that this draft is not meant to define an IDS/IPS style of functionality. We are only looking for how to solve the IPv6 firewall default on/off problem. This draft only covers the default list provided when the customer is begin connected. The customer can, depending on the ISP's policy, fully administer the firewall rules. Best Regards The authors; Eric Vyncke, Cisco Martin Gysi, Swisscom Guillaume Leclanche, Swisscom Ragnar Anfinsen, Altibox

IPv6 Only Network at RIPE 67
by Marco Hogewoning 21 Oct '13

21 Oct '13

"It's an IPv6 Working Group Initiative!" Dear Colleagues, Following the discussion at RIPE 66, the IPv6 Working Group is happy to provide you with an experimental network that is configured to offer only IPv6. This experimental network is not supported by the RIPE NCC or RIPE 67 Technical Team. We encourage everybody to connect to this network and test any websites, applications, hardware and software, and verify that they operate when an IPv4 address is no longer available. Important: This network is an experiment and is offered on a best-effort basis. We will try to maintain sufficient service levels and are happy to look into and help troubleshoot any issues you may encounter. If you rely on network connectivity for important business, we recommend you connect to the regular RIPE Meeting network. How to connect: - Make sure IPv6 is enabled on your device - Connect to SSID: IPV6ONLYEXP - Enter the password: iknowbesteffort The network provides NAT64 translation to connect to legacy services – please use the name server provided by the network to make use of this feature. We suggest you leave IPv4 enabled as this will be the scenario for most end users. Feedback: Please see Marco Hogewoning or Andrew Yourtchenko for any issues. We invite you to attend the IPv6 Working Group session on Thursday from 9:00-10:30 to discuss the results of this experiment. And of course you are welcome to follow up on this mailing list. Greetings, Marco Hogewoning Andrew Yourtchenko

New on RIPE Labs: RIPE Atlas - Packet Size Matters
by Mirjam Kuehne 02 Oct '13

02 Oct '13

Dear colleagues, This new RIPE Labs article (contributed by Emile Aben) talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets. Please find the detailed results on RIPE Labs: https://labs.ripe.net/Members/emileaben/ripe-atlas-packet-size-matters Kind regards, Mirjam Kuehne RIPE NCC

Update: SURFnet "Preparing an IPv6 Address Plan" document
by Nathalie Trenaman 27 Sep '13

27 Sep '13

Dear colleagues, The SURFnet manual "Preparing an IPv6 Address Plan" has been updated and is now available for download. https://www.ripe.net/lir-services/training/material/IPv6-for-LIRs-Training-… Since its initial release in 2011, this manual has proved to be one of the most popular downloads from the RIPE NCC website. It guides you through the steps you need to take to create an effective and comprehensive IPv6 address plan. The manual is aimed at network managers and network architects who are implementing IPv6 in their networks. It covers the following areas: - Introduction to IPv6 addresses - Options for working without an address plan - Preparing an address plan for a network - Detailed examples - Managing hosts We are delighted to have been involved with the production of this extremely useful and easy-to-follow guide. The RIPE NCC is committed to helping with the deployment of IPv6, and we believe that "Preparing an IPv6 Address Plan" is essential reading for all those who share that commitment. Kind regards, Nathalie Trenaman RIPE NCC

Draft agenda for RIPE 67
by MarcoH 18 Sep '13

18 Sep '13

Hello again, As we are getting closer to the 67th RIPE Meeting, our working group agenda is also taking shape. Thank you all again for your contributions, it is hard to fit them all in the 180 minutes we have got allocated. Please also keep in mind that this working group has a very broad charter, which includes anything that has to do with the deployment of IPv6. It doesn't have to come in the form of a ready made talk about a project you've done. We equally welcome any thoughts, comments or discussions on the topic. Especially also for those ideas that you think require input from the technical community or other items you want the RIPE community or the RIPE NCC to take action on. Here is the first draft of what we have in store, our sessions are split across Wednesday and Thursday again. The final order of talks is still to be confirmed, once we have had a chance to talk to our speakers and verify their availability. A) Welcome and Housekeeping B) Global State of IPv6 Deployment since IPv6 Launch Day - Geoff Huston (APNIC) C) Terastream IPv6 Details - Peter Löthberg (T-systems) D) NIC.CZ GEN6 Project - Zuzana Duracinksa (NIC CZ) TBC E) Report from the IPv6 Observatory Workshop (TBC) F) Small Scale Redundant IPv6 Uplinks without BGP - Benedikt Stockebrand (Stepladder IT) G) IPv6 Source Address, What Could Possibly Go Wrong? - Jen Linkova (Google) H) Moving on...IPv6, DS-Lite and PCP - Tassos Chatzithomaoglou (Forthnet) I) Exchange of feeback on Running an IPv6 Only LAN at the RIPE Meeting - Marco Hogewoning (RIPE NCC) & Andrew Yourtcheno (Cisco) Y) AOB Z) Thank you and goodbye As you can see we still have some letters spare, but we are running out of time to fill. So if you want some airtime please let us know ASAP using our regular address, which is IPv6 - WG - Chairs [at] RIPE [dot] net. Thank you all and see you in Athens (or at MENOG if you happen to be there), Marco Hogewoning on behalf of the working group chairs
