Dear Colleagues, We'd like to share some of the discussions from JANOG 34 held in Takamatsu-city, from 17-18 July with over 500 participants. While our discussions are in Japanese, we believe there are issues in common with operators outside Japan. An english version of the Summary Report and a report on anti-spam measures session is be made available this time, below. JANOG 34 Summary Report and "Let's talk about IP anycast" : http://goo.gl/IbKzkQ Pick up Session: "Measures against Spam after OP25B" : http://goo.gl/uY4lxk The topics discussed are not limited to these two topics of course. Please see the translated overview of the program and the presentation slides (in Japanese but some have visual images and data). Program Overview (English): http://goo.gl/KhrpRZ Program and Slides (Japanese): http://goo.gl/Q61oeh Here are some examples of the topics covered: * Use of technologies - Visualising network events - Advantages and disadvantages of "white box networking" * Operational issues - Blind spots of IPv6 PMTU Blackhole Discovery - NTP attacks: "NTP Talk WG": http://goo.gl/5RL50v - OpenSSL heartbleed bug - Stopping full table routing changed my life @ AS55394 * Social aspects - Seeking change in the cost structure of content delivery - Balance of outreach on security issues - What is good higher education for future engineers - Cultural differences in software and network engineers At the meeting, we ran the JANOG 34 network with IPv6 ULA-only and ULA + GUA SSIDs, which was presented at the IPv6 Operations session @ IETF90 in Toronto. ULA Experience at JANOG 34 http://tools.ietf.org/agenda/90/slides/slides-90-v6ops-1.pdf Positive findings - GUA + IPv4 (Private) and ULA is harmless (at least for MAC OS) - SLAAC/ULA and DHCPv6/ULA works well - ULA operation/configuration is not hard Challenges - Android devices did not come up without IPv4 - IPv4 only applications still exist (Skype/dropbox) - NAT66 on ULA only network should not be recommended , but it worked If you have any feedback, we welcome comments or questions on JANOG mailing list "janog@janog.gr.jp": https://www.janog.gr.jp/mailman/listinfo/janog/ * Subscription page first appears in Japanese but it's possible to switch to English from pull-down menu options on the top right The coming meeting, JANOG 35 will be from 14-16 Jan 2015 in Shizuoka Prefecture. We'll update you with more details through our SNS accounts as the date gets closer.
