To help students understand how the nameservers work together to form the DNS infrastructure, we will create a miniature DNS system called "DNS in a Box". As suggested by its name, the entire DNS system, which consists of multiple nameservers, runs inside a single machine. This is made possible by the container technology.
Even though this system is small, it has all the essential elements of a real DNS infrastructure. By building such a system, students will have a deeper understanding of how the DNS actually works. Although this lab is not a security lab, it is the basis for several SEED labs.
