DMARC Solution Applied to this Mailing List
by Adam Castle 18 Dec '17

18 Dec '17

Dear Working Group, As more email providers enable Domain Message Authentication Reporting & Conformance (DMARC), some people find they can no longer receive emails from the mailing lists they are subscribed to. We have deployed a Mailman setting change to address this problem. After consultation with the RIPE Working Group Chairs, we have enabled the DMARC "Munge From" setting on all RIPE mailing lists. This means that if your email service provider has DMARC enabled, you will continue to receive all emails sent to this mailing list, but the "From" part of the header will change. If you don't have DMARC enabled, you won't see any change to the emails you receive from this mailing list. You can find more information about how we have been handling DMARC in the following RIPE Labs articles: https://labs.ripe.net/Members/adam_castle/dmarc-and-the-ripe-ncc https://labs.ripe.net/Members/adam_castle/ripe-mailing-lists-and-dmarc To ensure all working group participants are aware of the changes, I am sending this mail to all working groups. If you have any questions or encounter any issues on this mailing list, please let me know. Many thanks. Adam Castle Web Services Manager RIPE NCC

New on RIPE Labs: IPv6 Week Denmark
by Mirjam Kuehne 22 Nov '17

22 Nov '17

Dear colleagues, An IPv6 week is an opportunity to raise awareness and stimulate IPv6 deployment on a national level. It brings a wide variety of stakeholders, knowledge and experience to a country where deployment of IPv6 is low. One of the key factors affecting the success of a national IPv6 week is support from the local community. In Copenhagen, we were very happy to have assistance from DKNOG in preparing and delivering this event. You can now find a report on RIPE Labs: https://labs.ripe.net/Members/nathalie_nathalie/ipv6-week-denmark Kind regards, Mirjam Kühne RIPE NCC

Looking for a secon opinion on using ULA along with GUA for residential access
by Radu-Adrian FEURDEAN 01 Nov '17

01 Nov '17

Hello, During the evaluation of a new model of CPE for our residential access we found one of the suppliers providing an option to announce a ULA prefix in addition to the GUA prefix obtained from DHCP-PD. I would like some second opinions regarding auch a practice. >From my point of view, if ULA is enabled: - it allows the client's LAN to stay IPv6-enabled even when the internet connection is down. It is a simpler version compared to the use of link-locals. - if the "auto" version of the setting is used, the ULA prefix will risk changing when changing the CPE, which is less than optimal. If ULA is disabled: - business as usual; when internet is down the client will only have RFC1918 (v4) + link-local (v6) So, is it worth enabling an additional ULA on the LAN ? -- Radu-Adrian FEURDEAN

Happy Eyeballs reporting
by JORDI PALET MARTINEZ 27 Oct '17

27 Oct '17

Hi all, After my presentation this week on Dubai about this topic, I got several folks telling me that they believe this is very interesting. Here is again the link to the document: https://tools.ietf.org/html/draft-palet-ietf-v6ops-he-reporting-00 And to the slides from this week: https://ripe75.ripe.net/presentations/129-ipv6-hev2-v2.pdf The major concern is privacy issues. My response to that is that we have the same when we log other protocols, including CGN, etc., in addition to that, for signaling the ISP that there is a problem, we don’t really need to log the complete source IPv6 address that doesn’t work, just the prefix, and also, we have a simpler alternative. If the logging is only for the destination IPv6 address and not the source one, I think in a big % of the cases, is sufficient for the ISP to know that there is some problem from its network to the failed destination (so the ISP could replicate the failure from any other source address in its network to the same destination). This logic, I believe, will only fail if the problem is specific to the “interior” of the customer network, which will be out of the scope of the ISP (and even do, the ISP will be able to tell the user --- hey this destination works from my network, not from yours, so something got broken inside your network). I’m going to submit a new version of this document on Sunday, so if you have inputs, please, let me know ASAP. Thanks in advance for your inputs !

RIPE75 - IPv6 fragmentation tool - Grafical solution - Opensource
by Stefan Jakob 25 Oct '17

25 Oct '17

Hi IPv6 Folks, Two colleagues of mine (Lorenz Schäfer under guidance of Jürgen Geinitz) created a grafical open source tool (python tk) to play around with your IPv6 space. The tool is inspired by Painting by Numbers presented at RIPE68 by Helge Holz. [1] --- README.md snip --- Description: This tool should make assigning of IPv6-address-blocks more manageable and easier to comprehend by showing the availible address space in an 8-bit matrix. In the left frame you can create radiobuttons, assigning them a name, colour and finally a certain address-space, which will be colored in the matrix and displayed in a label accordingly. --- README.md snap --- Since I am attending RIPE75 and some people didn't know about the tool, you chance to get a live demo today (maybe after the IPv6 WG) # long URL https://github.com/lorenz-schaefer/IPv6-address-space-fragmentation-tool # short URL https://goo.gl/KmyBLZ Rgds, SJ [1] https://ripe68.ripe.net/presentations/344-Painting_by_Numbers.pdf Beste Grüße, Stefan Jakob -- DENIC eG, Kaiserstraße 75 - 77, 60329 Frankfurt am Main, GERMANY E-Mail: jakob(a)denic.de, Fon: +49 69 27235-142, Fax: -235 https://www.denic.de Angaben nach § 25a Absatz 1 GenG: DENIC eG (Sitz: Frankfurt am Main) Vorstand: Helga Krüger, Martin Küchenthal, Andreas Musielak, Dr. Jörg Schweiger Vorsitzender des Aufsichtsrats: Thomas Keller Eingetragen unter Nr. 770 im Genossenschaftsregister, Amtsgericht Frankfurt am Main

Captive portal over IPv6

Dear all, I have a public WiFi service which connects people to internet via hotspot (captive portal). I want to assign IPv6 addresses to users in dual-stack, but my captive portal doesn't support. Do you know any captive portal that supports IPv6? Both hardware and software models works for me. Thank you -- Shahin Gharghi
