What Others Think

Am I wrong in thinking that "cat /proc/net/arp|grep eth0" provides basically the same information?

Or, even better: grep eth0 /proc/net/arp

That's wrong, /proc/net/arp contains the IP table. By example, I have IP address HW type Flags HW address Mask Device 0x1 0x0 00:00:00:00:00:00 * eth0 0x1 0x2 00:2e:e4:c5:91:7b * eth0 Another way is that : traceroute 2>/dev/null -n | awk '/^ [0-9]/{print $2;exit}'
