6to4 and Teredo relays deployment
by JORDI PALET MARTINEZ 29 Jun '07

29 Jun '07

Some weeks ago I started to work in documenting how to setup 6to4 and Teredo relays/servers in several platforms for the afripv6-discuss mailing list. There are many 6to4 relays already, but it becomes even more important to have them where the bandwidth is more expensive, because it avoids traffic going thru upstream links. The first message on this is here: https://lists.afrinic.net/pipermail/afripv6-discuss/2007/000061.html More information about 6to4 also available at: http://www.ipv6tf.org/index.php?page=using/connectivity/6to4 Similarly for Teredo: https://lists.afrinic.net/pipermail/afripv6-discuss/2007/000080.html And more info about Teredo at: http://www.ipv6tf.org/index.php?page=using/connectivity/teredo Regards, Jordi ********************************************** The IPv6 Portal: http://www.ipv6tf.org Bye 6Bone.

trans-Atlantic latency?
by Neal R 29 Jun '07

29 Jun '07

I have a customer with IP transport from Sprint and McLeod and fiber connectivity to Sprint in the Chicago area. The person making the decisions is not a routing guy but is very sharp overall. He is currently examining the latency on trans-Atlantic links and has fixed on the idea that he needs 40ms or less to London through whatever carrier he picks. He has spoken to someone at Cogent about a point to point link. What is a reasonable latency to see on a link of that distance? I get the impression he is shopping for something that involves dilithium crystal powered negative latency inducers, wormhole technology, or an ethernet to tachyon bridge, but its been a long time (9/14/2001, to be exact) since I've had a trans-Atlantic circuit under my care and things were different back then. Anyone care to enlighten me on what these guys can reasonably expect on such a link? My best guess is he'd like service from Colt based on the type of customer he is trying to reach, but its a big muddle and I don't get to talk to all of the players ...

Not from me/us, and not since ARIN existed or cared about usage ;-) Meer.net before it started operating a colocation company was a just- for-friends ISP business and they were given tons of IP space from their providers back in the mid-1990s and shared it around. What you have is Verio-assigned space. The colocation division came into being after ARIN existed and has always used strict allocation guidelines. -- Jo Rhett senior geek Silicon Valley Colocation Support Phone: 408-400-0550

Re: The Choice: IPv4 Exhaustion or Transition to IPv6
by Seth Mattinen 28 Jun '07

28 Jun '07

So we should deploy IPv6... I get it. The argument comes up time and time again. I would do it tomorrow - nay, today - if I had an answer to one thing: How the heck do I multihome? I have v6 space from Sprint to play with, but I'm reluctant to use it because I can't multihome with it. The end user doesn't care about 4 vs. 6, or anything we discuss here, all they care is that it *works*. It's all a magic box to them anyway. Businesses care that we can guarantee that it works. I want the same reliability with v6 that I have right now with v4, and single homed v6 isn't going to cut it, nor is some host-based hack, or every host gets a v6 address from each v6 provider, or stupid DNS tricks. Am I crazy to want routers to make the routing decisions? ~Seth

Routing Issue?
by Justin Scott 28 Jun '07

28 Jun '07

Good afternoon, is there anyone on the list from Cox communications? Many of our customers that use Cox in Arizona (Phoenix and Tucson specifically, 68.15.190.16 is one of the sources) are having trouble reaching our network in Tampa, FL (64.156.29.150 is one address here). This has been an intermittent problem for the last couple of days and I have not been able to get a direct contact who can help trace this issue. If there is anyone who can assist or knows of a known network break somewhere I would greatly appreciate it. Thanks in advance. -Justin Scott | GravityFree Network Administrator 1960 Stickney Point Road, Suite 210 Sarasota | FL | 34231 | 800.207.4431 941.927.7674 x115 | f 941.923.5429 www.GravityFree.com

Dancing turtles and possible future v6-only porn-repositories aside, I was recently recently wondering about another end-user v6 enticement that I'm sure must have been considered but which I haven't seen proposed before. I wonder what it would take to convince a major online retailer (Amazon?), an auction site (eBay?) or even transaction handlers (google checkout, paypal?) to put up v6 portals that offered across-the-board (or even select) discounts to customers coming in through their v6-only portal? Perhaps I'm simply too naive, but I would imagine that even a small % discount (from within the business' profit margin) would be incentive enough to get customers to at least start asking how they can get access to this cheaper IPv6 portal... (the lengths many people will go to to save a little money, often even spending more than they save in the process, is amazing in and of itself) ...I would think it would also cause additional publicity for the sites from the ensuing (even if only in the tech community) news reporting, and that there may even be future gov't incentives (write-off the discount?) for such practices. Just some thoughts... ~Aaron

Call for Presentations: NANOG 41 - October 14-16 - Albuquerque, NM
by Steve Feldman 28 Jun '07

28 Jun '07

The North American Network Operators' Group (NANOG) will hold its 41st meeting October 14-16, 2007, in Albuquerque, New Mexico. The meeting will be hosted by One Connect IP. This will be NANOG's fifth joint meeting with ARIN, the American Registry for Internet Numbers. NANOG will meet from Sunday to Tuesday, and ARIN from Wednesday to Friday, October 17-20. NANOG conferences provide a forum for information exchange among network operators, engineers, and researchers. Meetings are held three times each year, and include panels, presentations, tutorial sessions, and BOFs. NANOG solicits presentations highlighting issues relating to technology already deployed or soon to be deployed in the Internet. The NANOG community is invited to attend and participate in this forum, which offers numerous opportunities to share ideas, explore research and development, and interact with leaders in this important field of network operations. Vendors are encouraged to work with operators to present deployment experiences with the vendor's products and interoperability. General Session =============== The community is invited to develop panel sessions or present talks on topics relevant to the NANOG community, including: Network Operations Present-day operational case studies Everyday life in the NOC and tools of interest Exchange point technologies and implementation Peering/colocation coordination issues Content provider issues Security attacks/mitigation, tools, and analysis State of OAM tools for IP and MPLS networks Disaster recovery and planning Deployment Experience Mergers and their impact on interconnected networks Alternative and emerging last-mile technologies (metro/rural, broadband, radio, optical, etc.) VoIP deployment, architecture, peering, and interconnect Anycast IPTV Large-scale wireless Fiber and wavelength use by enterprises Research, Policy, and New Technology Approaches to securing the global routing system (e.g., s*BGP and/or other tools) Routing system scalability Capacity planning standards and tools Inter-provider MPLS/QoS/PCE RIR policy (e.g., implications of HD ratio) Active standards organizations and areas of interest IPv6: economics, deployments, and adoption rates Approaches to IPv6 scalability, e.g., Shim6 Talks ===== A general session talk should be on a topic of interest to the general NANOG audience, and may be up to 30 minutes long (including time for questions and answers.) Panels ====== Panel selection will be based on the importance, originality, focus and timeliness of the topic; expertise of proposed panelists; as well as the potential for informative and controversial discussion. The panel leader should provide an abstract describing the panel theme, list of panelists, and an outline of how the panel will be organized. After acceptance, the panel leader will be given the option to invite panel authors to submit their presentations to the NANOG Program Committee for review. Until then authors should not submit their individual presentations for the panel. A panel may be up to 90 minutes long. Lightning Talks =============== A lightning talk is a very short presentation or speech by any attendee on any topic relevant to the NANOG audience. These are limited to ten minutes; this will be strictly enforced. If you have a topic that's timely, interesting, or even a crackpot idea you want to share, we encourage you to consider presenting it. Signups for lightning talks will be accepted during the NANOG meeting. Research Forum ============== Researchers are invited to present short (10-minute) summaries of their work for operator feedback. Topics include routing, network performance, statistical measurement and analysis, and protocol development and implementation. Studies presented may be works in progress. Researchers from academia, government, and industry are encouraged to present. Tutorials ========= Proposals are also invited for tutorial sessions from the introductory through advanced level on all related topics, including: Disaster Recovery Planning Troubleshooting BGP Best Practices for Determining Traffic Matrices Options for Blackhole and Discard Routing BGP/MPLS Layer 3 VPNs A tutorial may use either one or two 90-minute sessions. BOFs ==== BOFs (Birds of a Feather sessions) are 90-minute informal sessions on topics which are of interest to a portion of the NANOG community. A typical BOF session includes some presentations, but usually is focused on community discussion and interaction. Frequent BOF topics include: Peering ISP Security Tools A BOF session is 90 minutes. Registration Fee Waivers ======================== The meeting registration fee will be waived as follows: - General session talk: one speaker - General session panel: one moderator and all panelists - Research forum talk: one speaker - Tutorial: one instructor - BOF: one moderator How to Present ============== The primary speaker, moderator, or author should submit presentation information and an abstract online at: http://www.nanogpc.org Once you have done this, you will receive instructions for submitting your draft slides. See http://www.nanog.org/presentations.html for complete submission guidelines. All submissions must include: Author's name(s) Preferred contact email address Submission category (General Session, Panel, Tutorial, Research Forum, or BOF) Presentation title Abstract Slides (attachment or URL), in PDF (preferred) or Powerpoint format (Slides are optional for BOFs.) You may instead submit the presentation information and draft slides in email to nanog-support(a)nanog.org. The deadline for proposals is Wednesday, August 1, at 11:59pm PDT. A limited number of slots may be available after that date for topics that are exceptionally timely, important, or critical to the operation of the Internet. Submissions will be reviewed by the NANOG Program Committee, and presenters will be notified of acceptance by mid-August. Final drafts of presentation slides will be due for review on October 4, with final versions for posting due on October 11.

where the wizards stay up late
by Travis H. 27 Jun '07

27 Jun '07

Not sure if this guy is still with us, but wanted to read "Confessions of a Hearing-Impaired Engineer", if anyone has a copy. BTW, "Where Wizards Stay up Late" is an entertaining book about the origins of the ARPAnet. It even has some of the first (hand-drawn, natch) network diagrams... Apparently, nuclear holocaust considerations did not really play much of a part in ARPAnet's genesis, despite folklore to the contrary. Withstand a nuclear war was not a design consideration (for most of the key players); any such properties were side effects of the real design considerations and decisions. -- "That is not dead which can eternal lie, and with strange aeons even death may die." - H.P.
