Methods and systems to detect topographic fraud are provided herein. The system includes a Cable Modem Termination System (CMTS) to periodically poll active cable modems and generate polling data. The system also includes a processor and a memory coupled to the CMTS. The processor is configured to, based on instructions in the memory, periodically determine a current geographic location for each polled cable modem based on the polling data from the CMTS, determine a geographic radius within which each polled cable modem is to be operated in and determine cable modems whose current geographic location is outside of their geographic radius. |
