Abstract

Systems and methods for detecting device change due to Dynamic Host Configuration Protocol (DHCP) in sparsely populated log data include monitoring and logging network traffic data; identifying one or more outlier time gaps associated with an Internet Protocol (IP) address used to communicate over the network within the logged network traffic data; and determining the occurrence of a DHCP change based on one or more network traffic characteristics of the IP address before and after the outlier time gap.
