Patent ID: 8832238

Claim:
A computer readable storage device storing instructions that, when executed by one or more components of a computing system, implement a dynamic host configuration protocol (DHCP) manager configured to perform operations including: recording internet protocol (IP) addresses for client devices in a network computed indirectly based upon one or more contacts of the client devices with a DHCP server by: extracting a subnet prefix and an interface identifier received in an information request from each of the client devices, wherein the information request does not comprise a request for an IP address; computing an IP address for at least a particular client device by concatenating a subnet for the particular client device with an interface identifier for the particular client device to generate the IP address for the particular client device; and storing the extracted subnet prefix and interface identifier in an event log; and exposing an analysis user interface for manipulation of the recorded IP addresses of the client devices to obtain utilization statistics for the network.
