Abstract: A technique for improving accuracy in an inventory containing assets associated with a network. Information pertaining to computer devices connected to a specified network is updated. Each device sends packets through at least one router in a set of routers, and each packet contains an element uniquely identifying its sending computer device. An inventory is maintained that identifies at least some of the computer devices as assets of an entity associated with the network. Data is acquired from ARP caches that are located within the routers. The acquired cache data is processed to detect all of the identifying elements that identify computer devices of the group. A database is constructed from information in the cache data that pertains to detected identifying elements. Information contained in the database is compared with information contained in the inventory to update the inventory.
