This paper presents a tutorial on building an IPv6 DNS Linux server that provides IPv6 name resolution as part of an IPv6 network. IPv6 is the next generation protocol designed by the Internet Engineering Task Force (IETF) to replace IPv4. IPv4 has been remarkably resilient. However, its initial design did not take into consideration several issues that are of importance today such as a large address space, mobility, security, autoconfiguration, and quality of service. To address these concerns, IETF has developed a suite of protocols and standards known as IPv6, which incorporates many of the concepts and proposed methods for updating IPv4. As a result, IPv6 fixes a number of problems in IPv4 and adds many improvements and features to cater for the future (Mobile) Internet.
