Internet Data Portal

Hi We’ve recently gone live with an open data site to publish whatever .nz related data that we can publish and any other useful Internet data - https://idp.nz For some years we’ve published IPv6 and DNSSEC stats but we decided it was time to publish that in a more useful way and include as much other data as we could. Initially we only have four datasets on the site: = .nz registrations data - a daily count of domains in each state and each transaction going back a few years (182,511 rows) = .nz Zonescan data - metrics from the monthly scan of all nameservers delegated to by the .nz zone (7,723 rows) This is where the IPv6 and DNSSEC stats come from. = ISPs - the Statistics NZ annual survey of ISPs sizes etc in a more usable format = Internet Connections - the Statistics NZ annual survey of ISP connections, datacaps etc in a more usable format If there’s any other data that we have that you think we could publish then please let us know and if you have any useful Internet related datasets that you’d like published then please get in touch as we’d be keen to help. cheers Jay -- Jay Daley Chief Executive NZRS Ltd desk: +64 4 931 6977 mobile: +64 21 678840 linkedin: www.linkedin.com/in/jaydaley

Thanks to everyone who offered advice - turns out the IBM server connect module in bay 2 of the chassis was the issue. Removing it from the chassis resolved all problems. It had nothing connected to it and all ports were disabled so I can only guess that its faulty. Thanks again, Andrew From: Andrew McBeath Sent: Tuesday, 8 September 2015 9:53 p.m. To: 'nznog(a)list.waikato.ac.nz' <nznog(a)list.waikato.ac.nz> Subject: Appeal to bigger brains I'm throwing this out there because I'm at a loss to figure out whats happening in our lab. I realise it's a bit outside the scope of this forum but as the subject line says I'm looking for some bigger brains - Beers are involved. We have an IBM blade chassis - only 4 blades at present - with a management VLAN 50 (192.168.10.0/24) and a data vlan 100 (10.10.10.10.0/24) hooked up to our prod network (10.10.1.0 and 11.11.1.0 -Yes I know this is BAD but I inherited the network and haven't been able to change it as yet) via a juniper SRX. Blades are running VMware 5.5 - no nic teaming as yet. All blades and AMM module (all on 192.168.10 addresses) can get to all parts of the network VMWare machine (Only one so far - on 10.10.10.0 network - can ping host, can ping external firewall, CAN ONLY PING ODD OR EVEN NUMBERED IP's DEPENDING ON WETHER IT HAS AN ODD\EVEN IP) ie if its forth octet is .125 it can ping .1, .3, .5 but if I change it to .126 it can only ping .2, .4, .6 Everything I've found online points to NIC teams in certain situations but none apply as the blades only have a single NIC enabled and the VM only has one NIC assigned. Appreciate any feedback Cheers, Andrew McBeath

They could have two VRRP sessions and forcing odd IPs to one and even IPs to another. scott _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog

Didn’t hit reply all.

I will try ripping it out and assigning a VMXNET3 adapter. In response to earlier replies. Kyle -No LACP – single uplink from the blade IO module to a single EX2200 Dylan/Liam – Exactly my first thoughts but 2 of us have been through every bit of kit between the VM and the rest of the network trying to spot what the other missed and are both at a loss. It’s not a complicated network. Will update tomorrow after I change the NIC.

(or is your issue with the host?) VMXNET3 is recommended however you probably need VMWare tools installed to use it. The E1000 and E1000e interfaces have some weird issues in network operation but not that I have seen as even and odd interfaces. On your network configuration in VMWare how many underlying interfaces are assigned to each V Switch? can you screenshot the V switches and the individual network config screens under properties. Sounds like their might be some odd check box or interface involvement that causes this issue.

Contribution for the IANA Stewardship Transition proposal
by Elly Tawhai 07 Sep '15

07 Sep '15

Hi NZNOG Community, The Numbers community is one of the key operational communities called on to develop its own proposal for the IANA stewardship transition. The below video relates to IANA Stewardship Transition: https://www.youtube.com/watch?v=t-x2nQxyDrU How you can contribute: ----------------------- 1. The CRISP team is seeking community response to its statement on the ICG plan, as announced at: https://www.nro.net/pipermail/ianaxfer/2015-August/000642.html The CRISP statement provides an excellent summary of the ICG proposal and how it satisfies the expectations expressed by the Numbers community. 2. The NRO has also recently called for community support of the ICG proposals, at: https://www.nro.net/news/iana-stewardship-transition-coordination-group-icg… 3. We encourage you to send an email to the ICG (public-comments(a)ianacg.org) to express your support for the ICG’s transition proposal. Kind regards, Elly APNIC

SDN APE, and IX stats from Citylink
by Tim Hoffman 04 Sep '15

04 Sep '15

Greetings, There was some discussion over the last couple of years with the NZNOG community at conferences and on the mailing list about Citylink doing a SDN based IX. This was to include with it Citylink releasing statistics of the aggregated traffic over their IX - a measure (published by most IXs) that many use to decide if it's worth connecting to an IX. Given the public nature of this discussion so far, and the fact that it's died off, can a representative of Citylink please confirm to the list; 1/ Is there an intention to move to some sort of SDN driven IX still, and if so what the timeframe for this will be? If this project has been abandoned, how will the IXs be developed in place of this project? 2/ Do they have any intention to publish an aggregated traffic on their IXs, and if so what the timeframe for this will be? I am sure many of us in the peering community will be eager to hear the answers to these questions.... Cheers, Hoff

APNIC Policy Proposal 114
by Jamie Baddeley 03 Sep '15

03 Sep '15

Folks, Saw this: https://www.apnic.net/policy/proposals/prop-114 Whilst the proposal does its best to outline pros and cons, I feel that from a policy perspective it removes the direct incentive to establish interconnectivity with IXP's (or some other mechanism for Multihoming). You gain an ASN but you are not compelled to increase the resilience of the Internet. To me that is a disadvantage that has not been stated. To me, having a network with an ASN means fundamentally you are participating in the mesh. On the solution: An organisation is eligible for an ASN assignment if: - they are currently multi-homed, OR - have previous allocated provider independent address space by APNIC, AND intend to multi-home in the future It seems to suggest a policy tilted towards incumbents or those who've been around long enough to have some PI space? The problem statement: The policy seems to imply that both requirements i.e. multi-homing and clearly defined single routing policy must be met simultaneously, this has created much confusion in interpreting the policy. Suggests that removing the confusing or conflicting elements of the current policy is wise, but I'm not convinced the proposed solution does that without undermining what I think is a important characteristic of the Internet which is a highly interconnected mesh. As an alternate, is it not better to strengthen the process to determine whether the applicant did indeed multi-home? There are downsides in that of course. It does place overhead on an entity to test that but what matters more? Ease of access into the ASN club or ensuring high levels of interconnectivity? What do others think? jamie
