how many bits are there in the ethernet address

An Ethernet (MAC) address is 48 bits long.

Quick Scoop

• The standard Ethernet hardware address is 48 bits.
• It is usually written as 12 hexadecimal digits (for example: 00:1A:2B:3C:4D:5E).

• Those 48 bits uniquely identify a network interface card (NIC) on a LAN, which is why the Ethernet address is also called a MAC address.
