MAC address (physical address)
The MAC address is the hardware address of each device that becomes a node on a LAN.
The MAC address is allocated to the Ethernet Interface Board inside the Module during
manufacturing.
Although the IP address is used to designate the final destination, the MAC address is used
to designate the network devices that must be passed through in order to reach the final
destination.
