MAC address structure
A1-B2-C3-D4-E5-F6
- A1-B2-C3：OUI给MAC制造商分配的地址段，每个厂商唯一。
- D4-E5-F6：MAC制造商自己分配，理论上在地址段内唯一。
- A1...F6：每组由两位十六进制数构成，范围从00~FF（十进制：0~255），共256个。理论上MAC地址共有组合数量为：256^6=281,474,976,710,656。
About
- MAC地址（MAC address）
- 英文：Media Access Control Address。直译为媒体存取控制位址，也称为局域网地址（LAN Address），MAC位址，以太网地址（Ethernet Address）或物理地址（Physical Address），它是一个用来确认网络设备位置的位址。在OSI模型中，第三层网络层负责IP地址，第二层数据链路层则负责MAC位址 。MAC地址用于在网络中唯一标示一个网卡，一台设备若有一或多个网卡，则每个网卡都需要并会有一个唯一的MAC地址。
- 组织唯一标识符（OUI）
- 英文：Organizationally unique identifier。在任何一块网卡（NIC）中烧录的6字节MAC地址中，前3个字节体现了OUI，其表明了NIC的制造组织。通常情况下，该标识符是唯一的。
