This command instructs the computer to loop (for /l) counting from 1 by 1 to 254 (1,1,254) and execute (do) a ping command with a count (-n) of 1 and a wait (-w) time of 100 milliseconds and the given network address and changing host (%i) address. From a Microsoft OS command line, Type for /l %i in (1,1,254) do -n 1 -w 100.For example, if the IPv4 Address is 192.168.1.101, this activity will assume that the host network is 192.168.1.0, and has potential host addresses from 192.168.1.1 through 192.168.1.254.Īctivity 2 - Perform a Ping Sweep For this activity, the host network will be assumed to be a 24-bit network based on the first three octets of the host IP address.
