随着互联网的快速发展,传统的IPv4网络已经面临着IP地址空间耗尽、骨干路由器路由表急剧膨胀、安全性差等问题。在不久的将来,IPv6必将取代IPv4,成为下一代互联网的核心协议。简要介绍IPv6产生的背景,并对IPv6具有的新特性进行阐述,同时分析IPv6网络可能面临的安全风险,并梳理一些应对策略。
With the rapid development of the Internet, the traditional IPv4 network has been faced with such problems as depletion of IP address space, rapid expansion of the backbone router routing table and poor security. In the near future, IPv6 will replace IPv4 as the core protocol of the next generation Internet. It briefly introduces the background of IPv6 generation and expounds the new features of IPv6. At the same time, it analyzes the security risks that IPv6 networks may face and sort out some countermeasures.
