-The hardware address of an [Ethernet] card. These are 6 bytes long (eg: 00:00:0C:1A:4B:C3).  
-  
-You have to 'reserve' part of the [MAC] address space when you make a network card, so everyone has a unique address. Since everyone's network card is unique, this is often used as a unique identifier for a machine (even though a machine may have multiple network cards, or not have one at all).

-An [Ethernet] packet header contains the source and destination [Ethernet] [MACAddress]es and a [Protocol] (or Length) field .  
-  
-You can find out the [MACAddress] of your network cards using the ifconfig(8) utility. For example in Linux:  
- ~$ /sbin/ifconfig  
- eth0 Link encap:Ethernet HWaddr __00:07:A9:11:40:A8__  
- ...

-It may look different in other [Unix] variants, [OpenBSD] shows the following:  
- $ /sbin/ifconfig -a  
- rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500  
- address: __00:05:1d:9b:f1:10__
