Bitstream 3a MAC limits
by Dave Mill 12 Mar '14

12 Mar '14

Hi all I know the answer to my question here is likely hidden deep in a PDF somewhere but someone on this list may know the answer off hand. I see that Bitstream 3a has a 64 MAC limit. What doesn't seem clear to me is if this MAC limit is a customer ONT port MAC limit, or a MAC limit for the entire customer S-VID. I had always assumed it was a limit on MACs that can be sourced from the customer ONT port but am I wrong? Is it a MAC limit on the total number of MACs that can be learnt over the entire customer S-VID (src'ed from either the provider or customer end of the link)? I'm extracting the 64 MAC limit from this document here - http://www.crownfibre.govt.nz/wp-content/uploads/2013/01/Chorus-UFB-Service… Any feedback, especially this afternoon, would be very useful. Provider is UFF. I am not really wanting to debate why someone would want that number of MACs over a BS3 connection and why some layer 3 should probably be involved here.... Cheers Dave

Hey guys, wondering if anyone from TVNZ On Demand is on this list and wouldn't mind contacting me offlist regarding problems streaming if a user has an IPv6 address. The helpdesk doesn't appear to know what ipv6 is so thought I'd try an alternative. Many thanks Barry

IPv6 redundancy
by Jonathan Spence 11 Mar '14

11 Mar '14

Hi all, I started a thread on the IPv6 group on LinkedIn in regards to this but.... What is the best way to provide redundant connectivity to SMBs with IPv6? Using v4 with NAT is easy with most routers but v6 is harder. Shim6 seems to be a good idea but looks to be a dead duck. People in that thread were advocating full AS and BGP but I don't think that is easy for most SMBs unless their IT support is top notch and trained (which lets face it, most don't even know how to screw in a lightbulb). It also may mess up global routing tables causing them to get much bigger. Any ideas? Jonathan Spence Chief Executive Officer Fixed: +64 9 9510448 Mobile: +64211055634

Turning on DNSSEC validation - you know you want to!
by Andy Linton 10 Mar '14

10 Mar '14

>From this posting: http://www.internetsociety.org/deploy360/blog/2014/01/circleid-dns-security… I like this quote: However, on the recursive resolver side, I am much more of a fan of having the DNS resolution occur as close to the end user as possible. This is particularly true when you enable DNSSEC validation.

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 held from 25-01-2015 to 30-01-2015 In 2016 NZNOG will be held in conjunction with APRICOT 2016, Auckland In 2017 NZNOG will be held from 22-01-2017 to 27-01-2017 In 2018 NZNOG will be held from
