by Felipe Barbosa 05 May '26

05 May '26

InternetNZ will begin a DNSSEC Zone Signing Key rollover in our *current* standby chain. This should not affect the active chain used in DNS resolution for .nz. The status and scheduling will be posted to status.internetnz.nz. This will consist of two maintenance windows, in each window we will pause zone distribution to make changes, perform validation, and resume zone distribution for the following zones: nz, ac.nz, co.nz, cri.nz, geek.nz, gen.nz, govt.nz, health.nz, iwi.nz, kiwi.nz, maori.nz, mil.nz, net.nz, org.nz, parliament.nz, and school.nz The first change window is on the following link: https://status.internetnz.nz/incidents/2f6mf7q6nh1w For questions or issues please contact registry(a)internetnz.net.nz, for updates please subscribe to the IRS Production > Zone Publish component of status.internetnz.nz -- Ngā mihi Felipe Agnelli Barbosa DNS Specialist InternetNZ | Ipurangi Aotearoa We are the home of .nz and we work for an Internet that benefits all of Aotearoa. www.internetnz.nz GPG: 95C1 8BDC EFA7 9CAC 303D 003E A058 2449 D152 8580

Conference Updates
by Richard Nelson 05 Mar '26

05 Mar '26

* This year is now the most popular NZNOG conference by far. Previously the largest NZNOG was 199 conference registrations (2025). This year we already have 236. Registrations are currently capped at 250 but we are talking to the venue and may raise this slightly. * The 30 years of RADIUS in 3 hours presentation on Wednesday had sold out. We have changed the room and been able to add a few more spaces. * A second JetEX Flight Sim - Post NZNOG event has been added since the first one had sold out. * All but two of the talk descriptions are now on the website. Talk submissions have been well ahead of previous years. See https://www.nznog.org/conferences/nznog-2026/talks Richard Nelson, for NZNOG Trust

NZNOG 2026 registration now open
by NZNOG 28 Jan '26

28 Jan '26

NZNOG 2026 registration is now open. We have some great tutorials this year - BGP operations by Philip Smith from NSRC, RADIUS by Alan DeKok, and Containerlabs by the Nokia folks. Last year we did a social thing on the Friday which we are repeating with a couple of options. We recommend getting accomodation sorted soon - as Christchurch can fill up suddenly. We have had some great talks proposed so far which will be going up on the talks page soon, and are keen for more. If you've done an interesting project, had an interesting fault, or have some ideas you want to share, please submit! Don't just leave the talks to the "big" operators and vendors, we are keen to hear from everyone. Info for all of the above is on the website. Registration: https://nznog-2026.lilregie.com/ Conference website: https://www.nznog.org/conferences/nznog-2026 -- Nathan Ward on behalf of the NZNOG team

Minimizing the BGP Flap Storm risk in NZ ... can I ask a favor?
by Barry Greene 10 Nov '25

10 Nov '25

Hi Team, Some know me, some don’t. I’m asking as someone who has been around BGP security/resiliency for a while. We have a risk in the industry that we can all prevent - by deploying the BGP session security tools whenever we configure BGP sessions. Our Problem: We have ~274,000 BGP sessions open to anyone in the world who wishes to initiate a low-level DDoS attack to disrupt the BGP session. New Zealand currently has ~470 open BGP sessions. The Risk: A BGP Session knockdown risk model exists that can target an organization, an ISP, a whole country, or the entire Internet. Is this a serious risk? About a year ago, I conducted a Shadowserver Ops review with one of the major US broadband companies. I shared with my peers working there that they had ~60 BGP IPv6 sessions open to the risk (no iACLs, no ACL on the device, no control plane protection, no GTSM, etc). They have been part of tabletop exercises where “BGP Flap Storm” was used as one of the plays. Once informed, they resolved the issue within 40 minutes through an emergency ACL deployment. The ask: Deploy the basics of BGP Session Security on all your existing BGP Sessions. Talk to your peers on the other side of the BGP session to fix their BGP Session security (remember, BGP session re-establishment could happen from either side). Update your processes, procedures, and SCRIPTs to include BGP Session security (one of my theories is that people are using scripts to deploy that are not complete). If you need a complete breakdown of which routers on your network have their BGP session open, take the simple route and sign up for the Daily Shadowserver reports on your network. They are free for you. I’ve locked down many ISPs’ security risks just by using the Shadowserver reports. Just go to this link to subscribe: https://www.shadowserver.org/what-we-do/network-reporting/get-reports/ Sincerely, Barry Greene Old Security Geek WhatsApp/Signal +1 408 218 4669. PS - I’m asking this just in New Zealand right now because I live here (now) and wondering if we could knock out this risk …. Or is the potential of a BGP Flap Storm knocking out Telecom something we have to just live with?
