IEEE OUI and Company_id Assignments<\/a> is a list of manufacturers and corresponding codes which are used in MAC addresses and protocol identifiers:<\/p>\n

The three-octet OUI can be used to generate Universal LAN MAC addresses and Protocol Identifiers per ANSI\/IEEE Std 802 for use in Local and Metropolitan Area Network applications.<\/p>\n

If your firm manufactures or plans to manufacture products using ISO\/IEC 8802 standards, you should apply to IEEE for your firm’s OUI. The Institute of Electrical and Electronics Engineers, Inc. has been designated by the ISO Council to act as the registration authority for the implementation of International Standards in the ISO\/IEC 8802 series. This is the one world-wide source of registered OUIs. <\/p><\/blockquote>\n
