The MAC address consists of 12 hexadecimal characters, which equals to 48 bits. A node also needs a MAC address, but not just an IP address for networking. The IP address is not called the hardware address, as the MAC address refers to the hardware address. The MAC address of a device can be changed, but not permanently. OUI is not an element of the IP address, it refers to the first 3 bytes (24 bits) of the MAC address which identifies the manufacturer of the network interface card.
