Abstract

An apparatus and method for managing device information through networks. The apparatus for managing device information through networks includes a polling list for storing polling information including device IP addresses assigned to home devices, polling intervals, and last polling times; a poller for checking the polling list and sending out a polling list listing devices to be polled; and a message processor for generating a polling message based on received registration request messages from the home devices, sending out the polling message verifying whether corresponding devices are activated with reference to the polling list, and updating the polling information stored in the polling list based on a response message with respect to the polling message received from the home devices. As different polling intervals are used with respect to devices existing on a home network, the reliability of device information improves and network traffic reduces.
