	I'm sure you got a bazillion answers to this alreadybut just for fun
this is one way to do it (though up in less than 30 seconds) -

# arping -f -I eth0 $ipnumber | grep Unicast | awk '{print $5}' | tr -d /\[\]/

	No, it's not the best way to do it, but I like sticking awk in anywhere
I can regardless of necessity.  :-)
