| Abstract: | The Domain Name System (DNS) plays a critical role in the proper function- ality of the Internet. Subsequently, a number of tools have been created to take measurements that can be used to understand better how it operates in practice. One aspect of the design of such tools is the query distribution among nameservers. While the designers of the tools do take into consid- eration and discuss this, there seems to be a lack of in-depth analysis of how the queries are distributed. In this paper, we make a comparison of two active DNS measuring tools, OpenINTEL and ZDNS, and how their recursive resolvers distribute queries. Despite their different objectives and design choices we try to make a fair comparison. We captured enough network traffic and analysed it. By scanning a million domain names we were able to capture enough network traffic to analyse. Based on the data collected we set a few key metrics to examine the extent to which the distribution of queries is fair, meaning more even. This study concludes that OpenINTEL has an overall more even distribution of queries which is indicated by the majority of metrics. |
