A MAC address is represented by how many hexadecimal digits in total?

MAC addresses are 48 bits long, and when written in hexadecimal they appear as 12 digits. Each hexadecimal digit encodes 4 bits, so 12 digits × 4 bits equals 48 bits in total. You’ll typically see them as six pairs like 00:1A:2B:3C:4D:5E, which confirms there are 12 hexadecimal digits. If you used 8 hex digits, that would be 32 bits; 16 hex digits would be 64 bits; 24 hex digits would be 96 bits. So 12 digits is the correct representation.
