Abstract

A system and method are disclosed for the automated discovery of devices on a network, such as a TCP/IP network using Dynamic Host Configuration Protocol (“DHCP”) and Domain Name System (“DNS”) servers. Devices on the network may be discovered, identified, and tracked by a monitoring server. Communications with the monitoring server may include identification information for each device. The identification information may be stored in DHCP option fields, transmitted with DHCP messages, and used to identify whether the device is new to the network.
