A MAC address comprises a total of 12 hexadecimal digits.

MAC addresses use 48 bits in total, organized as six 8-bit octets. Since one hex digit represents 4 bits, you need 12 hex digits to cover 48 bits (12 × 4 = 48). That’s why a MAC address is typically written as six two-digit hex numbers (often separated by colons or hyphens), amounting to 12 hex digits in all. For reference, 8 hex digits would be 32 bits, 16 hex digits would be 64 bits, and 32 hex digits would be 128 bits, which are lengths associated with other identifiers, not a standard MAC address.
