The Domain Name System (DNS) makes the Internet usable by translating readable names such as rwth-aachen.de into IP addresses. It originated from simple lists of names and developed into a globally distributed, hierarchical system. Today, it fulfils many more tasks – for example in the areas of e-mail, IT security and network management. The DNS also plays a central role at RWTH Aachen University and is protected by modern technologies such as DNS firewalls. This article provides an overview of the origin, structure and current significance of the DNS.
