The detection of devices with duplicate media access controller (MAC) addresses in a cable network. A cable modem (CM) having a MAC address is connected by the cable network to a cable modem termination system (CMTS) having a gateway interface address. A centralized storage of historical cable modem MAC address/giaddr pair data is used to identify cable modems (CM's) that report duplicate MAC addresses. A server tracks the CM MAC address/giaddr pair data of all CM requests that it receives and stores the MAC address/giaddr pair data into a datastore (such as a database). When a CM seeks to access the network, the server looks into the datastore to determine whether the CM MAC address of the CM has previously been stored with a different associated giaddr, which would imply that there are multiple CMs attached to different CMTSs where the CMs share the same MAC address. If such duplication is detected, appropriate remedial response is taken.
