The Research of the IPv6 Network Intrusion Detection System Wang Xing-zhu (Hunan University of Arts and Science Hunan Changde 415000) Abstract: With the rapid development of network technology, network infrastructure gradually becomes the most important part. At present, although the network security of more and more research attention, but the hacking incident has increased every year. Intrusion Detection Technology is a very important network security technology, and IPv6 as the next-generation Internet protocol, is bound to experience long-term coexistence with IPv4 and eventually completely replace IPv4 development process. Now in IPv6 research and development environment, the use of intrusion detection system is very necessary and timely. Keywords: IPv6; Network Security; Intrusion Detection; Packet Capture
