How many bits are in each IPv6 address hextet?

Explanation:
Each IPv6 address hextet is 16 bits. This comes from the fact that a hextet is four hexadecimal digits long, and each hex digit represents 4 bits. So 4 digits × 4 bits each equals 16 bits per hextet. An IPv6 address has eight such groups, totaling 8 × 16 = 128 bits. The other sizes don’t fit the structure of a single hextet: 8 bits would be a byte, 32 bits would be a 32-bit word, and 64 bits would be a larger word, none of which match the size of an IPv6 hextet.
