Abstract
Dynamic IP addresses may be automatically identified and their dynamics patterns may be analyzed. Multi-user IP address blocks are determined as candidates for further analysis. An entropy score is determined for each IP address in every candidate block to distinguish between a dynamic IP and a static IP shared by multiple users. IP addresses with high entropy scores are grouped, and then analyzed, and may be used in various applications, such as spam filtering.
