An Ethernet address, also known as a MAC (Media Access Control) address, is 48 bits long. This 48-bit binary number is typically expressed as 12 hexadecimal digits, with each hex digit representing 4 bits, making it convenient to display and use

. To summarize:

• Length: 48 bits (6 bytes)
• Representation: 12 hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E)
• Structure: The first 24 bits identify the manufacturer (Organizationally Unique Identifier, OUI), and the last 24 bits uniquely identify the device assigned by the manufacturer

This 48-bit length allows for a globally unique identifier for network devices on an Ethernet LAN
