A MAC Address is comprised of how many total hexadecimal digits?

A MAC address is a fixed length value of 48 bits. Since each hexadecimal digit represents 4 bits, 48 bits require 12 hex digits (48 / 4 = 12). A MAC is also organized as six bytes, and each byte is shown as two hex digits, giving 12 digits in total. That’s why you’ll see standard MAC addresses written as six pairs like 00:11:22:33:44:55. While there are longer formats in some contexts, the classic MAC address length is 12 hexadecimal digits.
