"Some of us are old enough to remember a day when the Internet existed only as a Department of Defense research project called the Arpanet. Back then there were few enough hosts on the Net that they could all be listed in text files stored on each Internet-connected host. The /etc/hosts file on Unix systems originally served that purpose -- it contained a list of the names of all the computers on the Net, and associated those human readable names with their machine readable IP (Internet Protocol) addresses. So when a human typed in any computer's name, that computer's matching IP address could be instantly looked up in /etc/hosts."
"Whatever group you fall into, having a working understanding of DNS is crucial. Luckily, it's also pretty straightforward. Creating the files used by DNS, starting one or more DNS servers, and configuring how, when, and if your systems use DNS is easy, especially under Linux."
"In this story we give a general overview of the DNS system, how it's implemented on Linux, and how to configure it. We describe the files that hold the configuration information and host database and where they're located. Sample configuration files are also included to get you started with your own DNS setup."
