The nature of data exchanged between DNS (Domain Naming System) servers and resolvers has been changed since the introduction of IPv6 (Internet Protocol version 6) because of the increased address length and other technical enhancements. These changes and recent security concerns raise questions against fundamental design principles of the DNS protocols, especially to the transport layer and the payload size. In this paper we review how DNS protocols will be affected by the requirements and productionlevel deployment of IPv6, and how the new requirements for larger-size transfer should be satisfied by enhancing and/or redesigning the existing DNS transport layer protocols. 著者：力武健次, 野川裕記, 田中俊昭, 中尾康二, 下條真司
