A vs AAAA
by Mark Foster 11 May '14

11 May '14

Hello learned NZNOG-folks, Many of you have been working hands-on with IPv6 a lot more than I have, so i'll ask this here. In two cases, on two discrete systems, both Windows clients (one a Windows 7 workstation, the other a Windows 2008R2 server) a 'ping'[1] is run against a hostname. In both cases a ping against a v6 IP address is tried (and failed, as the host has no v6 connectivity - and in at least one case, v6 is actually disabled in the network interface settings). A simple 'nslookup' check without specifying the query type returns both IPv6 and IPv4 responses for the hostname. So why is the client trying to ping a v6 address when it has no v6 connectivity? (and for the record, an answer of 'make v6 work' doesn't solve my problem, as much as it might be a simple resolution.) Cheers Mark. [1] as you can probably guess, ping isn't actually the end-use of this connectivity, but it was the first troubleshooting measure used. This is impacting on application-layer connectivity, so 'use-v4-only' ping syntax also doesn't help me. :-)

Average Usage Per Service
by Skeeve Stevens 11 May '14

11 May '14

Hey all, Just doing some math and capacity planning and I am wondering what others use for numbers for the average usage of a service per user? I am working with NBN-like speeds of 12mb, 25, 50 and 100. Back in the day I used to factor it in at around 30% when we were doing dialup and low-speed DSL... and on ADSL2 I normally factored it at around 15%. But I am wondering what people use for NBN-like speeds. I am thinking that a percentage is probably not a realistic measurement anymore as there is no particular reason a 25, 50 or 100mb user would do more or less on average... they just have the capacity to do more. Does anyone else have any thoughts they are willing to share, or even real observations across a significant number (thousands) of customers that they use for bandwidth (agvc and/or transit) planning? Feel free to off-list if you want to keep the information anonymous... I am happy to publish some findings and a spreadsheet for the use of others. Thanks all. ...Skeeve *Skeeve Stevens - *eintellego Networks Pty Ltd skeeve(a)eintellegonetworks.co.nz ; www.eintellegonetworks.co.nz Phone: +612 8014 7398; Cell +61 (0)414 753 383 ; skype://skeeve facebook.com/eintellegonetworks ; <http://twitter.com/networkceoau> linkedin.com/in/skeeve twitter.com/theispguy ; blog: www.theispguy.com The Experts Who The Experts Call Juniper - Cisco - Cloud - Consulting - IPv4 Brokering

Best Practice - prefix advertisement
by Alexander Neilson 06 May '14

06 May '14

Hi All At $Dayjob I have been working around an aggregation bug in our routers and manually specifying prefix’s at the three levels we operate (/22, /23, /24) and using prefix filters to advertise /24’s to APE / WIX, /23’s to our domestic transit, and only the /22’s to international transit as a method of Traffic Management / Traffic Engineering to utilise cheapest links available. I have been exploring the looking glass services of a number of entities to see what propagates to them (that they enter into the forwarding database) and I am seeing some entities (who announce peering at APE for example) having the /22 and /23 routes in the LG outputs and following the /23 path in trace route. I am asking for two fold information. Can someone / everyone point me at their best guide to BGP “Best Practice” regarding advertising prefixes? and also can I get people’s specific advice about what they accept / do to announcements before entering them into their routers as accepted routes and what they would expect to see advertised to ensure my goals are reached. I made these changes to help reduce my contribution to the ballooning of the global routing table but I also don’t want to go to extremes on polluting the APE routing table by advertising the 12 /24’s plus the 6 /23’s and the 3 /22’s. Also can I get consensus information (or peoples opinions) about am I abusing / dis respecting APE with my announcements and how I should structure my announcements to be a respectable citizen here while providing the best hints to my preferred handling of traffic? (and feel free to let me know if I should just announce the /22’s and accept that some people choose to prioritise other paths) Thank you in advance for any input, feel free to reply off list.

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 2014 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[1].

2 of 3 IPv6 DNS servers broken?
by Pete Mundy 27 Apr '14

27 Apr '14

Dear list Is anyone from Snap network ops watching who is involved in IPv6 or DNS? I'm not officially a Snap customer yet (1 week to go) so I guess trying to put this through the helpdesk might not be the best approach. Just wanted to give you guys a heads up really that only 1 of the 3 published NS appear to be responding to DNS queries via IPv6 (but they do all respond to ping6). See transcripts below. They were taken from a Snap UFB link. It all works fine via v4. I guess maybe others on the list with native v6 could test to confirm that this is also the case as seen from elsewhere? Eg perhaps from a non-Snap link? My v6 visibility is still a bit limited. Just a Raspberry Pi stuck behind a Fritzbox on Snap UFB for testing. Maybe something is 'on the fritz'?!
