Additionally, there are three possible ways to express MAC addresses, see the example below. For example, HP’s OUI is 3C:D9:2B and Google’s OUI is 3C:5A:B4. The other 24 bits are specific to each manufacturer and are assigned by the IEEE Registration Authority Committee. The first three octets (24 bits) are called Organisation Unique Identifiers (OUI). The number is split into six octets with each octet having 8 bits. The number is also 48 bits long and sometimes referred to as a 6-byte hexadecimal. A typical MAC address can be shown as 2C:54:91:88:C9:E3. MAC addresses are assigned in a hexadecimal format which is a 12-digit number. Also, it is unique in that no 2 devices can have the same MAC address. Recall that we said MAC addresses are assigned by the manufacturer of the device and cannot be changed.

This is exactly why MAC addresses are only important to the Local Area Network (LAN) and are not relevant to the data stream that leaves the LAN. The MAC address identifies a device locally whereas an IP address identifies the device globally.

These are both used to identify a device but they do it differently. In order to facilitate communication between devices on a network, two types of addresses are necessary: MAC addresses and IP addresses.

How? See, each network interface in the device must have its unique MAC address paired with it. Important to note is that one device, such as a laptop, can have multiple MAC addresses. This is done by the manufacturer during production and cannot be changed. The MAC address is attached to the Network Interface Card (NIC) on all devices that can connect to the internet. Technically, a MAC address can be defined as a physical address that uniquely identifies a device on a specific network. MAC is an acronym for Media Access Control and is also known as Burned In Address (BIA) or physical address or hardware address.
