Have to run as superuser... but easier and more informational if you are looking for actual devices. Need to install arp-scan.

Alternatives

There are 16 alternatives - vote for the best!

You send a unicast ICMP packet to each host. Many firewalls will drop that ICMP. However, in order to send the ICMP, you'll have first done an ARP request and the remote machine is unlikely to ignore that, so the computer will be in your ARP table.

Know a better way?

If you can do better, submit your command here.

What others think

great and much faster than nmap ping scan.

i had to specify the interface

arp-scan -l -I wlan0
