Research On Heuristic IPv6 Addresses Scanning Target Generation Technology Based On Address Structure

IP address scanning obtains the corresponding network information of the target by calling the port service and recording the response of the target.The obtained information can be used for research on network security management,network topology analysis,and address location.Currently,IPv4 address scanning technology is getting mature.Compared with the IPv4 address space,the IPv6 address space is huge and the density of active addresses in the IPv6 address space is low,which makes the traversal address scanning technology used in IPv4 address scanning unsuitable for IPv6 networks.At the same time,the current scanning efficiency of the IPv6 scanning target generation technology is low.Aiming at improving the problem of the low scanning efficiency of IPv6 scanning target generation technology,this paper proposes a heuristic IPv6 address scanning target generation algorithm based on address structure according to the characteristics of IPv6 address allocation management and statistical characteristics.The algorithm mainly involves a three-part process of the pre-scanning mechanism,IPv6 active address direct inference algorithm,and IPv6 active address extension algorithm.And based on the algorithm,this paper designs and implement a heuristic IPv6 address scanning target generation system based on address structure.The system consists of three parts:data collection layer,data processing layer,and data display layer.The data processing layer is divided into three parts,the pre-scanning module,the scanning detection module,the direct inference algorithm module,and the extended algorithm module.This paper uses open-source data as input to test the algorithm and the system.Experimental results show that the accuracy of the scanning target address generation algorithm has been improved,and the system can implement the function of generating the scanning target address set.
