IP Address from MAC Address - how?
If I know the MAC address of a piece of hardware that is on my subnet, how do I get its IP address? (I use DCHP so the IP address can move around).
I know I can ping all address on my subnet and then have a look at the ARP table (arp -a command). But I want to directly get the IP address by knowing the MAC.

You could have DHCP assign a specific IP address based on MAC address. Most(all?) implementations of DHCP allow for this.
