NZNOG 2026 was held in Christchurch in March 2026. The NZ national community has a long track record of innovation, both in technology and in the underlying investment models for its network infrastructure. Here's a summary of some of the sessions that I found to be of interest.

It's fading from our collective memory, but almost thirty years ago the global IT industry was gripped by Y2K fever. Another version of the counter rollover problem is coming back in 2036, 2038 and 2040. Hopefully we will avoid a large amount of hysteria this time around!

For some time, I have been looking after a routing analysis report called the "". Here I'd like to explain the reasons for this report, and what is in the report and share some thoughts as to its usefulness today to the Internet routing community.

Today's digital world relies on a consistent view of the time. We achieve this with the Network Time Protocol (NTP). Given the extent of our reliance on an accurate time base it is surprusing that the NTP protocol has no security mechanisms to protect the integrity of time dissemination. Lets look at time, NTP and the recent efforts to add authenticity and temper detection to this protocol.

The whois query tool is useful to identify which organisation holds an IP Address Prefix or an Autonomous System Number, but not so useful in performing the reverse query, listing all IP Addresses and Autonomous System Numbers held by an organisation. Here is a resource that can help with such queries.

It's time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself.
