Back in October 2018 we blogged about the upcoming DNS Flag Day, and how it could potentially affect .nz domains. As InternetNZ regularly tested .nz domains »
Within the Technical Research team, we have developed many data workflows in a variety of projects. These workflows normally need to run on a schedule, contain »
This is a follow-up post to summarise the work of resolver detection presented at DNS-OARC 29. We built a classifier that can tell, with certain probability, »
In this blog post, we introduce the upcoming "DNS Flag day", how it will affect .nz domains and how .nz compares to other ccTLDs. »
As the DNS operator of .nz, we manage 4 of the 7 .nz nameservers ourselves and we've been collecting their DNS traffic. The other 3 are »
My previous post "Source Address Classification - Feature Engineering" introduced the background of the source address classification problem and a critical part of the »
This is a follow-up post on registrant classification. Before reading this post, make sure to check out Registrant Classification using Machine Learning. In the last post, »
I’m currently attending the ICANN organisation’s Global Domains Divison (GDD) Industry Summit being held in Vancouver, Canada. Arriving to warm weather, soaring mountains and »
Problem background As we operate the authoritative name servers for the .nz ccTLD (Country Code Top Level Domain), we observe more than 500k unique source addresses »
An important task in text data mining is text classification/categorisation. The objective, is to start with a training set of documents (e.g. newspaper articles) »
An interesting request we received after the register size prediction presentation at the Registrar Conference earlier last year, was a suggestion of applying similar methodology on »
As part of our efforts to understand the .nz namespace better, we started at the beginning of 2017 to check domains for the presence of a »
As we run the .nz ccTLD (Country Code Top Level Domain) authoritative nameservers, we receive lots of DNS queries and answer each query with a DNS »
In my previous two posts, we've seen how to model domain retention prediction and new creates forecasting. Those are essential model components required for a register »
The Domain Name System is a distributed database with a hierarchical structure. A complete DNS resolution is a time-consuming process composed of iterations of network communications »
