Abstract

A method for identifying devices on a network using a two-step process of first scanning a range network addresses for devices and then acquiring device information from each of the accessible devices. The method involves scanning the network for devices by sending a request to each of a plurality of network addresses, receiving a response from one or more of the devices, obtaining a hardware address for at least some of the responding devices, and identifying the device based on the hardware address. A user interface is provided to display the results of the scan along with the more specific identifying information for some or all of the responding devices.
