[We apologize for multiple copies.] ************************************************************* OPEN AGGREGATED DATASETS AND STATS ON DNS (.NL ccTLD) https://stats.sidnlabs.nl/ *************************************************************
SIDN Labs[1] is happy to announce our new stats and open aggregated datasets to the Internet/Research/DNS communities. It provides: * Visualizations of the DNS traffic for .nl, which is the country-code top-level domain (ccTLD) for the Netherlands. It also contains stats on domain registrations, DNS queries, DNSSEC usage, plus layer-3 and layer-4 information. * Longitudinal data: the data we provide are continuous and longitudinal (starting from May 2014), and daily updated. * The respective datasets in JSON format. * URL: https://stats.sidnlabs.nl/ Currently, we only provide aggregated data and visualizations, which means that we do not offer PCAP/Netflow datasets, similarly to the former Internet2 Netflow Weekly report[2]. However, if you have a novel research idea that would improve the security and stability of the Internet and would require our data, then let us know so that we can consider sharing some of the underlying data with you (subject to our privacy framework and EU and Dutch privacy laws [3]). Mail us at sidnl...@sidn.nl. ABOUT SIDN AND SIDN LABS: SIDN[1] manages .nl, the Internet's country-code domain for the Netherlands. As the Dutch national domain name registry, we enable Internet users all over the world to register.nl domain names and use them safely. We operate the .nl zone of the Domain Name System (DNS) and handle over a billion DNS queries a day for the 5.5 million-plus registered .nl domain names. More than 2.4 million of those domain names are secured with DNSSEC, making .nl the largest secured Internet extension in the world. We operate our own DNS anycast network to maximise the availability of the .nl zone and we provide backend services for .aw (Aruba, a Dutch overseas territory) and .amsterdam. SIDN Labs[4] is SIDN's research and development team, which develops and evaluates new technologies and systems with a view to further enhancing the stability and security of .nl, the DNS and the wider Internet. DATA DESCRIPTION The data were obtained by analyzing the DNS traffic received on one of our authoritative name servers for .nl. They represent approximately 10 per cent of the total traffic, or about 130 million queries per day. Please note that most of the traffic comes from DNS resolvers, which are typically located at ISPs/CDNs, and not from end users. Data interpretation: Please be aware that, due to DNS caching by the resolvers operated by ISPs and CDNs, the data are actually a sample of all the .nl queries generated by clients. Data format: The data are made available in JSON format. Data processing: We use our Hadoop-based ENTRADA platform and our Domain Registration System (DRS). ENTRADA[5] is an acronym for ENhanced Top-level domain Resilience through Advanced Data Analysis. The goal of the ENTRADA platform is to develop new applications and services with a view to further increasing the security and stability of .nl, the DNS and the wider internet. ENTRADA enables us to store all the DNS queries received on our authoritative name servers. Automated analysis of the stored data helps us to quickly detect threats and anomalies.
