| 6.2.2 | Basic hexadecimal (hex) numbering
Hexadecimal is a Base 16 numbering system that is used to represent MAC addresses. It is referred to as Base 16 because it uses sixteen symbols; combinations of these symbols can then represent all possible numbers. Since there are only ten symbols that represent digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), and the Base 16 requires six more symbols, the extra symbols are the letters A, B, C, D, E, and F. The position of each symbol, or digit, in a hex number represents the base number 16 raised to a power, or exponent, based on its position. Moving from right to left, the first position represents 160, or 1; the second position represents 161, or 16; the third position, 162, or 256; and so on. Example: 4F6A = (4 x 163)+ (F[15] x 162)+ (6 x 161)+ (A[10] x 160) = 20330 (decimal)
