Conference wifi usage?
by Richard Hector 11 Apr '12

11 Apr '12

Hi all, Hopefully this isn't too off-topic, or too vague ... If one was running wifi for a conference - not for IT types - does anyone have an idea what the likely usage of wifi by participants would be, on a per-user per-day basis? There will probably be beer, but unfortunately I can't invite you all. Is mentioning that necessary to get past the filter? Thanks, Richard

Re: [nznog] CAIDA's 2012 IPv6 survey -- need network operators to fill out

Hi all: CAIDA have a project that needs some real data on IPv6 deployment, and are running a survey to gather it. Operators, when you have a spare moment (!), it would help CAIDA a lot if you'd fill in the survey, as described below ... Thanks, Nevil (U Auckland | CAIDA) ----- Forwarded message from Amogh Dhamdhere <amogh(a)cc.gatech.edu> ----- Subject: Re: CAIDA's 2012 IPv6 survey -- need network operators to fill out From: Amogh Dhamdhere <amogh(a)cc.gatech.edu> Date: Wed, 4 Apr 2012 15:41:19 -0700 Cc: nanog(a)nanog.org To: k claffy <kc(a)caida.org> X-Mailer: Apple Mail (2.1251.1) Hello folks, Thanks much to those of you who already completed our IPv6 deployment survey.

AusNOG 2012 Call For Presentations
by Matthew Moyle-Croft 08 Apr '12

08 Apr '12

Call for presentations for AusNOG 2012 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Langham Hotel **Melbourne** 6 & 7 September, 2012 Notes =-=-=- The AusNOG organisers have decided to change the name of the conference to reflect the year instead of the number of the event. So this year's conference is going to be known as AusNOG 2012. It's hoped this will remove some confusion. AusNOG 2012 is being held in Melbourne for the first time. The organisers encourage Melbourne based network operators, especially those that have not previously attended an AusNOG, will take advantage of this opportunity to not only attend the meeting but also present! Topics =-=-=-= Internet operations can be a broad topic and the presentation selection committee will be short-listing presentations in the following focus areas: * Improving the redundancy/resiliency/sustainability of your network * Making leaps in service or network availability * Taking the network operations BCP to the next level * Using 'offline' communications tools to keep the network working * How technology is changing network architectures * Evolution in network architectures and scaling issues Other topics which are of interest to the network operator community are also welcome at AusNOG 2012. Naturally, presentations of a marketing nature are not welcome at this technical event. Notes to presenters =-=-=-=-=-=-=-=-=-= Preference will be given to presentations that result in actual operational outcomes. Session speakers should be prepared to present for 30 minutes. Keynote speakers will be expected to present for 45 minutes to 1 hour. Short presentations of strong operational content are also acceptable. Once the final slides are submitted, changes will only be permitted where the presentation requires the most up to date information or data. By submitting a presentation for consideration in the AusNOG 2012 programme, and if selected the presenter will allow AusNOG to: * Take photographs of the presentation and presenter. * Record and rebroadcast video and audio of the presentation and presenter. * Redistribute, the presentation slides, audio, video, and photographs electronically, on the AusNOG website, or otherwise but leaving all intellectual property in the hands of presenter or rightful property holder where possible[1]. Deadlines =-=-=-=-=- 01 June: Submission of presentation title, presentation description (300 words), and presenter biography (200-400 words) 15 July: Presenters notified of their acceptance status as an AusNOG 2012 presentation. August 29: Submission of final presentation slides as Portable Document Format (pdf), PowerPoint, or Keynote. Provision of a recent digital photograph (<500k) of the presenter. All submissions must be sent to organisers at ausnog.net. A separate call for lightning talks will be made closer to the AusNOG 2012 event [1]: AusNOG accepts that some speakers are unable to allow us to archive their presentation due to company or corporate policy, and if the situation arises AusNOG will delete all copies in its possession after the presentation.

NZRR Route Registry Update
by NZRR Database Notifications 03 Apr '12

03 Apr '12

Dear Colleague, This is to notify you that one or more objects in which you are designated for notification have been modified in the NZRR routing registry database. These objects are used to configure the various NZIX route servers (http://nzix.net/) so you can expect the relevant servers to be reloaded in the near future. The reloading of the servers is staggered over a period of time so that if you are peering with both servers at an exchange, you can maintain at least one BGP session at all times and consequently a full set of routes.

DNS TTL Mangling
by Cameron Bradley 31 Mar '12

31 Mar '12

Hi All, It has come to my attention in the course of moving the DNS for a number of domains that several of the ISPs in this country are mangling the TTLs on records queried by their recursive DNS servers. This behaviour seems to me to be undesirable in situations where someone may have set a record to a shorter TTL to facilitate smoother movement between hosting providers. In the cases I'm seeing, records with TTLs of 14400 are being handed out with TTLs of 86400 by the service provider's servers. How common is this practice, and what are the benefits to the SP from doing it? From my perspective there is also the concern that this, for all intents and purposes appears to be bad practice, and serves to 'break' DNS in itself. Regards, Cameron Bradley

.nz domain stats

Hi Folks, Just updated my spreadsheet with the past couple of years of .nz stats in case anyone is interested. No web page this time because Excel 97's save webpage feature sucks. http://jedi.school.nz/nzdg/nzdg-1993-feb2012.xlsx Cheers, Blair
