Because while 8 characters of hexadecimal stored directly as themselves as individual bytes occupy 8 bytes, each pair of hexadecimal characters only encodes up to 1 byte of binary information. 00 -> FF only covers 0-255, which is the range of binary values representable in 1 byte. The bit length they're talking about isn't about how many characters are in the human readable IDs (hex) but instead the technical range limit of the ID numbers. |
