Communications on the Internet use the Internet Protocol (IP). This protocol allows all hosts to communicate with their own unique IP addresses. This means you could contact other hosts by entering that unique number. Humans, however, are not too good at working with numbers, and that was one of the most important reasons why the Domain Name System (DNS) was developed. The purpose of DNS is to translate IP addresses to names, and vice versa. In this chapter, you'll learn how to create a DNS server on SUSE Linux Enterprise Server.
