LAN MapShot quickly discovers devices in your local switched Ethernet broadcast domain. Discovered devices include IPX servers, routers, and hosts, and all IP and NetBIOS devices (switches, servers, routers, printers, hubs, hosts, and Fluke Networks tools). To see devices in multiple broadcast domains, LAN MapShot must be run within each broadcast domain either by running LAN MapShot on a PC that is physically within that domain or by plugging into the various domains at the hub using a laptop computer. Broadcast domain is a term used to denote a LAN with a common address space, which is demarcated from other broadcast domains by routers. It is the set of devices that can be reached by sending a message that uses the MAC (Media Access Control) broadcast address (FFFFFFFFFFFF). Devices belonging to the same broadcast domain receive all broadcast packets from other devices in the same domain.
