  • accessing an ARP (Address Resolution Protocol) table from at least one device on the network;

    using each accessed ARP table to identify other devices on the network;

    identifying additional devices on the network by;

    sending at least two batches of pings to addresses of devices that have not been identified in accessed ARP tables; and

    after sending each batch of pings, waiting an interval for responses from any devices at the addresses to which the pings were sent;

    wherein the step of sending a batch of pings comprises sending pings to multiple addresses without waiting for responses until all the pings have been sent to the multiple addresses.
