Send a ping to each IP on a subnet

Question

Is there a command line based way to send pings to each computer in a subnet? Like

for(int i = 1; i < 254; i++)
    ping(192.168.1.i);

t

Answer 1

for i in $(seq 1 254); do ping -c1 -t 1 192.168.11.$i; done

Adding a -t 1 waits only one second before exiting. This improves the speed a lot if you just have a few devices connected to that subnet.
