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。
