identifying the MAC address of the network interface of the media device using a mapping of internal IP addresses to MAC addresses.
8. A method for monitoring media devices that are connected to a local area network (LAN) hosted by a router located at a panelist household, the method comprising:
detecting, by a network communications monitor installed at the panelist household, a media device that is connected to the LAN, wherein the network communications monitor is connected to the router via a network interface of the network communications monitor, and wherein the media device is configured for receiving media from a media provider for presentation at the panelist household;
identifying, by the network communications monitor, a media access control (MAC) address of a network interface of the media device;
determining, by the network communications monitor using the MAC address, that the media device is a new device that has been added to the LAN; and
based on determining that the media device is a new device that has been added to the LAN, transmitting, by the network communications monitor to an audience measurement entity via the network interface of the network communications monitor, a new-device alert, wherein reception of the new-device alert by the audience measurement entity enables the audience measurement entity to contact a panelist of the panelist household to inquire about the new device.
9. The method of claim 8 , wherein determining, using the MAC address, that the media device is a new device that has been added to the LAN comprises:
determining that the MAC address of the network interface of the media device is absent from a list of MAC addresses associated with panelist media devices of the panelist household; and
based on determining that the MAC address of the network interface of the media device is absent from the list of MAC addresses, determining that the media device is a new device that has been added to the LAN.
10. The method of claim 9 , further comprising:
after transmitting the new-device alert, receiving, by the network communications monitor from the audience measurement entity via the network interface of the network communications monitor, data indicating that the the media device is a panelist media device associated with a panelist of the panelist household; and
based on receiving the data, adding, by the network communications monitor, the MAC address of the network interface of the media device to the list of MAC addresses associated with panelist media devices of the panelist household.
11. The method of claim 10 , further comprising:
inspecting, by the network communications monitor, traffic passing through the router;
