ABSTRACT
IPv6 off ers the potential of achieving increased scalability, reachability, endto-end interworking, Quality of Service (QoS), and commercial-grade robustness for data communication, mobile connectivity, and for Voice Over IP (VoIP)/tripleplay networks. Th e current version of the Internet Protocol, IPv4, has been in use
successfully for almost 30 years and exhibits some challenges in supporting emerging demands for address space cardinality, high-density mobility, multimedia, and strong security. Th is is particularly true in developing domestic and defense department applications utilizing peer-to-peer networking. IPv6 is an improved version of IP that is designed to coexist with IPv4 while providing better internetworking capabilities than IPv4.
