![]() See this article for the definition of local and universally administered MAC addresses. If the universally administered MAC addresses are not enough for all of the networking interfaces, locally administered MAC addresses which are derived from universally administered MAC addresses are assigned to the rest of networking interfaces. Here, ‘generate’ means adding 0, 1, 2 and 3 (respectively) to the final octet of the base MAC address. ![]() Only the first one of them (which is called base MAC address) is stored in eFuse or external storage, the others are generated from it. The final octet of each universally administered MAC address increases by one. Several MAC addresses (universally administered by IEEE) are uniquely assigned to the networking interfaces (Wi-Fi/BT/Ethernet). ![]() Number of universally administered MAC address ¶
