802c - Local Medium Access Control (MAC) Address Usage
The full title of this standard is "Standard for Local and Metropolitan Area Networks: Overview and Architecture Amendment: Local Medium Access Control (MAC) Address Usage".
This amendment to IEEE Std 802 will provide an optional local MAC address space structure to allow multiple administrations to coexist. This structure will designate a range of local MAC addresses for protocols using a Company Identifier (CID) assigned by the IEEE Registration Authority. Another range of local MAC addresses will be designated for assignment by local administrators. The amendment will recommend a range of local MAC addresses for use by IEEE 802 protocols.
Currently, globally unique MAC addresses are assigned to most IEEE 802 end stations and bridge ports. Increasing use of virtual machines and Internet of Things (IoT) devices could exhaust the global MAC address space if global MAC addresses are assigned. These applications could use local MAC address space, but in that case some applications require independent address administration (e.g. virtualization systems and protocol specific address mappings). This project will provide conventions and enable protocols that will allow multiple stations or servers to automatically configure and use local MAC addresses without conflict when multiple administrations share a local address space. Such protocols will allow virtual machines and IoT devices to obtain a local MAC address without centralized local MAC address administration.
