The MAC48 class is used turn a 48-bit MAC address into concrete
a data type. A MAC (Media Access Control) address is a hardware 
address that uniquely identifies each node of a network. Ethernet 
hardware addresses are 48 bits, expressed as 12 hexadecimal digits. 
The first 24 bits of the MAC address consist of a unique vendor code
which should match the vendor of the network interface card.
