Forcing use of streaming meter as alternate gateway to facilitate media-exposure measurement
A method and system to facilitate measuring of media exposure. An example method comprises a streaming meter on a LAN configuring a host device on the LAN to use the streaming meter as a default gateway of the host device, including the streaming meter acquiring assignment from a router on the LAN of all IP addresses assignable by the router, to prevent the router from functioning as a DHCP server for the host device, and the streaming meter then responding to DHCP messaging from the host device to assign an IP address to the host device and set the host device to use the streaming meter as the default gateway of the host device. In the example method, the streaming meter then monitors network traffic of the host device that flows through the streaming meter and reports the monitored network traffic to a media-measurement platform to facilitate media-exposure measurement.
