Or you could just check your router.

….or you could just type arp -a from the command line?
# arp -a
Net to Media Table: IPv4

This works in windows, as well.

Why not just look at the DHCP leases on your router? No third party software needed.

Geekmaster:

For arp – a to show the devices on the loal network the hoats actually have to have sent data to each other. In other words the hosts must have contacted each other at some point in time.

Try this….run arp -a and look at the output then put a host on the network without “talking” to it. run arp -a again and you won’t see it.
Ping it and then run arp -a again and it will show up.

I think that’s why this program works. It must ping all adresses in the net range and then arp -a to see what shows.
