What is a MAC address? What is OUI?

A MAC address is a unique identifier for network interfaces. It is a 48-bit number (12 hexadecimal characters). They can either be written in either of these formats:

MM:MM:MM:SS:SS:SS
MM-MM-MM-SS-SS-SS

An OUI {Organizationally Unique Identifier} is a 24-bit number that uniquely identifies a vendor or manufacturer. They are purchased and assigned by the IEEE. The OUI is basically the first three octets of a MAC address. For example, these are examples of OUI:

00:00:0A -- this is owned by Omron
00-0D-4B -- this is owned by Roku, LLC
