Since January 2011, IPv4 address space has exhausted and IPv6 is taking up the place as successor. Coexistence of IPv4 and IPv6 bears problem of incompatibility, as IPv6 and IPv4 headers are different from each other, thus, cannot interoperate with each other directly. The IPv6 transitioning techniques are still not mature, causing hindrance in the deployment of IPv6 and development of next gen...

After almost two decades of IPv6 development and consequent efforts to promote its adoption, the current global share of IPv6 traffic still remains low. Urged by the need to understand the reasons that slow down this transition, the research community has devoted much effort to characterize IPv6 adoption, i.e., if ISPs and content providers enable IPv6 connectivity. However, little is known abo...

During the transition from IPv4 to IPv6, it is necessary to provide IPv6 access service for IPv6 islands inside the native IPv4 network to access the native IPv6 network. The existing IPv4/IPv6 transition methods make IPv6relay gateways maintained by IPv6 service providers become potential communication bottlenecks. In this paper, a new method PS6 is presented to reduce the reliance on these re...

To cope with the various problems arising from Internet protocol such as scarcity of IP addresses in the Internet and increase in the number of paths, research and development has been conducted on IP version 6 (IPv6) as a next generation Internet technology. Telecommunications Advancement Organization (TAO) has upgraded Japan’s nation-wide Gigabit Network (JGN: Japan Gigabit Network) to be com...

With the assignment of the last available blocks of public IPv4 addresses from Internet Assigned Numbers Authority, there is continued pressure for widespread IPv6 adoption. Because the IPv6 address space is orders of magnitude larger than the IPv4 address space, researchers need new methods and techniques to accurately measure and characterize growth in IPv6. This thesis focuses on IPv6 router...

IPv6 technology introduced to solve problems in the previous IPv4 technology. New threats were discovered due to the exploitation of flaws in IPv6 architecture design. There is a demand to produce new intrusion detection technique for new threats of IPv6 network environment. In this paper, the method of features selection to produce the most significant feature is presented. The objective of th...

IPv6 is the next generation internet protocol which is gradually replacing the IPv4. IPv6 offers larger address space, simpler header format, efficient routing, better QoS and built-in security mechanisms. The migration from IPv4 to IPv6 cannot be attained in a short span of time. The main issue is compatibility and interoperability between the two protocols. Therefore, both the protocols are l...

This paper presents auto-networking technologies for IPv6 mobile ad hoc networks. The auto-networking technologies consist of IPv6 unicast address autoconfiguration, IPv6 multicast address allocation, secure multicast DNS, and service discovery. These technologies are based on IPv6’s inherent autoconfiguration facility, which can provide ad hoc users with automatic networking in IPv6 ad hoc env...

Mobile IPv6 is considered to be one of the key technologies for realizing mobile Internet which enables seamless communication between fixed line and wireless access networks. In this paper, we introduce the basic concept of Mobile IPv6 and describe the detail procedure of handoff of mobile terminal. We analyze its effectiveness of Mobile IPv6 handoff by using Network Simulator 2 and constructe...

In this paper we present an overview of the IPv6 activities of European National Research and Education Networks, both within the individual national programmes and in joint studies undertaken within the GÉANT Task Force for Next Generation Networks working group. The group has an international testbed activity (GTPv6) under which many IPv6 aspects have been studied, including routing, interope...
