FACA: An effective method for detecting the survivability of large-scale IPv6 addresses.

IPv6 address scanning is the basic technology of IPv6 network measurement and security. In recent years, there has been some researches focusing in address scanning of IPv6 network. However, most of them are aimed to reduce the address space, not to improve the scanning efficiency for a given large address set. In this paper, we analyze different ways of IPv6 address configuration and their corresponding address features, and then introduce a mapping model between IPv6 addresses and network devices. Furthermore, we propose an adaptive scanning strategy based on target types. The large-scale IPv6 addresses to be scanned will first be divided into different subsets according to their characteristics, and then the adaptive strategy will call the appropriate scanning method for different subsets. Experimental results show that the method has better accuracy and efficiency in detecting the survivability of large-scale IPv6 addresses.
