mac地址的构成

mac地址是目前很多智能家居得企业都需要申请的，知倍客从事mac地址申请时间比较长，为很多企业服务过。但是企业并不清楚具体是mac地址的由来。下面知倍客将为企业介绍下mac地址组成方面的知识。 IEEE RA标识符分配 The MA-S assignment includes the assignment of the OUI-36 that is the base for the assigned EUI-48 and EUI-64 extended identifier blocks. The MA-S does not include assignment of a 24-bit OUI. The 24 initial bits of the assigned MA-S block is an OUI assigned to the IEEE RA. The MA-M does not include assignment of an OUI. The assignee of the MA-M may create an OUI-36 as the first 36 bits of an address in the MA-M assignment block. If the assignee of an MA-M needs a unique 24-bit organization identifier, a CID assignment is recommended. The first 24-bits of the assigned MA-M block are an OUI assigned to IEEE that will not be reassigned. The MA-L assignment includes the assignment of the OUI that is the base for the assigned EUI-48 and EUI-64 extended identifier blocks. An MA-L is equivalent to an OUI assignment made prior to January 1, 2014, which also included assignment of both an OUI and the associated blocks of EUI-48 and EUI-64 identifiers.
