IPv6 Residential Deployment Survey
by John Curran 24 Jan '19

24 Jan '19

NANOGers - If you are providing residential Internet service with IPv6 (or are a customer of same), please take a moment to complete Jordi’s survey - this will help provide insight into the actual technical practices being used in residential IPv6 deployment. More details in attached email - Thanks! /John Begin forwarded message: From: John Curran <jcurran(a)arin.net<mailto:jcurran@arin.net>> Subject: [arin-ppml] IPv6 Residential Deployment Survey Date: May 22, 2016 at 6:24:17 AM GMT+2 To: ARIN PPML <ppml(a)arin.net<mailto:ppml@arin.net>> Folks - Jordi Palet Martínez is conducting a brief survey regarding IPv6 deployment in residential Internet service. Having insight into the various practices that are in use may help to inform IPv6 number resource policy development, and thus I ask that you take a moment to complete the survey if you are providing such services (whether production or trial basis.) Jordi notes - "The results will be published and updated every month or so - No personal data will be published. (If you know your network, it takes less than 2 minutes to complete it) The survey can be responded even if is not yet a commercial service, and customers can also respond, not just the ISP. However, to avoid duplicate data, make sure to include the country and ISP name.” The IPv6 Residential Deployment Survey may be found here - <http://survey.consulintel.es/index.php/175122> Thanks! /John John Curran President and CEO ARIN

A survey about networking incidents
by Yu, Minlan 24 Jan '19

24 Jan '19

Hi Nanog, We all know that networks are at the heart of many of the systems we use today. When these systems break, the underlying networks are often the first suspects. Networks are hard to diagnose and they are most likely to be blamed for problems even if they are completely healthy. As networking engineers, we have all seen cases where another part of the system was causing an issue but the network was held the suspect until the problem was resolved. We are researchers from Harvard and The University of Pennsylvania who are interested in understanding this problem and its impact better in order to build a solution. Our goal is to be able to quickly rule out the network as a root cause for incidents in order to be able to speed up diagnosis and also to improve operator efficiency. We are interested in learning the answer to a few questions. Specifically, we would like to know: How often do you see problems where the network is blamed but after investigating you find the problem to be caused by some other part of the system? How often have you had incidents where the cause of the incident was outside of the boundary of your organization? How much do you think fixing this problem can help you and your organization more quickly diagnose problems? We have created a *very* short survey to be able to get an operator's perspective on these questions. It should take less than 15 minutes to finish. The findings should help us as well as the research community at large to be able to build a solution that can benefit all types of networks, of different sizes, to improve how they do the diagnosis. We will be presenting the results of this anonymous survey in a scientific article later this year. We will report back our research once it's finished. Survey URL: https://docs.google.com/forms/d/e/1FAIpQLScx-U54eQFQi5AdBCOOucMaI6BVmLwcMFi… We would greatly appreciate it if you could help us with this research. Please feel free forward this survey to other operators you know. Thank you! Minlan Yu http://minlanyu.seas.harvard.edu/

IPv6 NAT64
by Art Stephens 23 Jan '19

23 Jan '19

I know this might be off topic but hopefully not too far off. I heard rumors that there are ISPs out there running IPv6 only networks where the clients can still get to the IPv4 world without the $30,000 plus dollar expense of buying a NAT64 appliance to service 4,000 plus customers. Anyone have some insight into this? -- Arthur Stephens Senior Network Administrator Ptera Inc.

DWDM 10ms failover
by David Williams 23 Jan '19

23 Jan '19

I'm looking for some real world feedback on 10ms DWDM failover times from Omaha to Denver on 10Gbps transmission waves. I have seen several documents that report 10 ms failure detection time but I suspect the failover mechanism takes some time to react and propagate the failed state across multiple nodes in what is probably at least 600 mile cable routes with multiple nodes along the way. Is that kind of performance something we could realistically expect? This email and any files transmitted with it are confidential and intended solely for the designated recipient.
