With no flags, the program displays the current ARP entry for hostname.

Is there a way to get a MAC address from an IP address
Is there a way if given an IP address to get the MAC address. The problem I am having is that there are two nic's that are using the same IP address on my network, but the error message my FBSD box gives me is only the MAC address for the offending card. I belive that the offending card does have another ligit IP address. I do have a map of all IP that respond on my network, but do not have a way of knowing which IP goes with which MAC address. Any help would be appreciated.
