Some discussion starters from APRICOT 37
by Michael Fincham 09 Mar '14

09 Mar '14

Hi all, I recently had the pleasure of attending APRICOT 37 (many thanks to the NZNOG and InternetNZ folks, and others, who made this possible!) and felt that there were some interesting topics discussed that may be worth bringing back to the NZNOG community. Here's an unsorted and terse list of some things I thought worthwhile: -> We need to stop looking at Alexa's "top 100" websites for IPv6 support and being disappointed - we need to be looking at a much smaller proportion of the "top sites" as this is where "all of the traffic" is actually going. Facebook, YouTube, Google, Wikipedia, Akamai and GGC cache nodes. It's a port 80 world and a few sites dominate :) -> Some big providers (T-Mobile, Telstra AU) talked about having rolled out IPv6 in various forms (single stack v6, dual stack with CGNAT on v4 and native v6) to their mobile subscriber base with approximately no support impact. A common theme: "We need to test IPv6 before deploying it!" "What testing did you do with IPv4?" "None" "Well do that with IPv6 too!" -> Paraphrasing: "Customers don't know what IPv4 is to begin with, so they sure don't know or care what IPv6 is." -> These operators reported seeing /40%/ of the traffic on any given subscriber where dual stack was available going straight out to the native v6 Internet! This is a huge win if you're looking at deploying CGNAT as it means approximately half as much state needs to be kept on your expensive CGNAT boxes, and half as much traffic is being molested on the way from the customer to the 'net :) It also means you should definitely be rolling out dual stack alongside your CGNAT :) -> 464XLAT (http://tools.ietf.org/html/rfc6877) looks like it's about to be a big deal in the mobile IPv6 space. In short, 464XLAT allows for phones to run single stack native IPv6 while applications on the phone can continue to access v4 literals etc if required. Makes use of a clever combination of existing technologies. Only Android 4.3+ supports this so far, but more phone support shouldn't be far away. To me this looks like it would be a killer feature to have on fixed line CPEs, though I am unclear how it would interact with the type of NAT these CPEs typically perform (though this ought not be too far away from a tethering scenario on a phone). -> Geoff Huston's closing presentation on the state of BGP in 2013 contained some interesting measurements and insights about how worried we should be able router performance and so on. The video (https://www.youtube.com/watch?feature=player_detailpage&v=e4N9ELoM76M#t=1798) and slides (https://conference.apnic.net/data/37/2014-02-27-bgp2013_1392943641.pdf) are worth a look if you have ~ 20 minutes. Since the NZNOG list has been more alive of late, I'd welcome discussion on any of these points as certainly there is plenty here that is relevant to NZ :) -- Michael Fincham System Administrator, Unleash Office: 0800 750 250

ICONZ-Webvisions (NZ) to close Open DNS Resolvers
by Mark Foster 05 Mar '14

05 Mar '14

Hi folks ICONZ-Webvisions (the entity formerly known simply as ICONZ in NZ) will be blocking external access to our recursive DNS servers to non-customer subnets on the evening of 6 March 2014. In the knowledge that there may well be former customers or third-parties who have hard-coded the IP's of our DNS servers into their configs (or their customer configs) I'm giving notice now; the following IP's will cease to provide DNS resolution to clients outside of our network space, at that time: 210.48.65.1 210.48.65.2 210.48.66.1 210.48.66.2 Customers with concerns about this change are invited to contact our Customer Care team on 0800 843 638 or via support.nz(a)iconz-webvisions.com<mailto:support.nz(a)iconz-webvisions.com>. Regards Mark. -- Mark Foster Technical Services Manager - Australia & New Zealand [iconz-webvisions-logo-png] www.iconz-webvisions.com<https://webmail.iconz.net/owa/redir.aspx?C=ToykmhkSsEaPr3XJN6nrf-rRV-b9iM8I…> ICONZ-Webvisions, ICONZ House, 60 Airedale Street, Auckland 1010, New Zealand

NZNOG 2014 videos
by Richard Naylor 05 Mar '14

05 Mar '14

Folks I just noticed an upgrade to the video player software had taken away the SD/HD control, or at least it wasn't explicitly obvious. There is a newer version that is slightly better, but I've rolled back a release so that SD/HD is obvious. Comments/feedback appreciated. They can be off list to save clutter. Also is HD worth it ?

NZNOG conference dates for the next hundred years
by Dean Pemberton 03 Mar '14

03 Mar '14

Hi All >From time to time we run into people who claim that we keep moving the NZNOG conference dates around. Normally this is because NZNOG happens to conflict with another conference that they might want to go to. The official policy is.. "The last full usable week in January" I'm just about the give the NZNOG update at the APRICOT meeting in Kuala Lumpur. So I thought I'd solve the problem once and for all. Here are the conference dates for the next hundred years along with a script to check which a particular year. I might have a couple of these wrong and we do reserve the right to change them if required, but they are a good place to start. #!/usr/bin/perl -w use strict ; use DateTime ; use feature qw( say ) ; my $year = $ARGV[ 0 ]; my $dt = DateTime->last_day_of_month( year => $year , month => 1 ) ; while ( $dt->day_of_week != 5 ) { $dt->subtract( days => 1 ) ; } my $nznogenddate = $dt->dmy; $dt->subtract (days => 5) ; my $nznogstartdate = $dt->dmy; print ("In $year NZNOG will be held from $nznogstartdate to $nznogenddate\n") ; $ for i in `seq 2015 1 2115`; do ./dates.pl $i ; done In 2015 NZNOG will be

OT: Ethernet
by Richard Naylor 28 Feb '14

28 Feb '14

Been some celebrations recently over ethernet. Going from 10Mbps to 100Gbps over 40 years. http://www.eetimes.com/document.asp?doc_id=1263267&page_number=1 You might find it interesting reading. The call for participation in 400Gbps ethernet was made about a year ago. Interesting points (other than the historical stuff) + 10G NICs will surpass 1G in 2015. Interesting to see fall of 100Mbps. + Graph showing ATM fall off and rise of ethernet in Telco cores. Hilarious from my point of view. The first switch at CityLink was a dual ethernet/ATM one. We never had much of an ATM network because we couldn't afford the second switch ! A shareholder did loan us two, but they were multi-mode fiber and so wasn't much use. No customers wanted ATM due to the cost. None of the telcos took us seriously because we used ethernet. About 6 or 7 years later both Telecom and Clear developed ethernet products. Occasionally we showed people our pole mounted ethernet switches, running PoE, but no one really understood it. James Watts in PNN did and ran some of it. Cheaper fiber replaced it. We also had pole mounted Linux routers that we used for WiF point to point links. Another story.

Hi! Know I am some small fry on the list, but your help would be appreciated. This would be useful in talking to my ISP about some PMTU issues that I am having re a VPN going over PPPoE, with MTU 1480. Thanks! Matt Grant
