The Domain Name System is an integral part of the Internet. It provides the basis for converting names of systems into IP addresses and back again, as well as pointers to other resources such as mail handlers and system aliases. However DNS has grown beyond a simple look up service into a major piece of Internet infrastructure that goes beyond its original scope. This article will provide an overview of the evolution of DNS and provide insight into the current developments and controversies in this arena. While it won't solve any of the issues it should give the system administrator and Internet user some idea of what the current issues are with respect to domain name service.
