Tiivistelmä
Domain Name System (DNS) is a major part of the modern-day Internet. Understanding how the system works is beneficial for anyone in the IT field. DNS is present everywhere and can cause issues if it is not understood properly. Misconfiguration of DNS servers may cause outages and other issues for the users. This thesis provides an in-depth overview of the DNS system, including its hierarchical structure and core principles.
The study presents a method for analysing massive amounts of DNS query data using ENTRADA2 software, showing its capabilities in providing insight into the network. Additionally, it explores prior research made by different universities and organisations, which shows how DNS analysis has evolved into a global collaborative effort.
In addition this thesis examines challenges faced with DNS query data analysis, which include technical and operational limitations. Also exploring potential future developments in the field. The study shows that ENTRADA2 is an effective tool for processing and enriching massive amounts of DNS query data and with proper hardware, real-time analysis is possible.
