A "hextet" in IPv6 consists of 2 bytes, or 4 hexadecimal digits (as in the example in the question), or 16 bits.
The largest number of bits a CPU can process is word size. A CPU's Word Size is the largest number of bits the CPU can process in one operation.
a general rule for binary is that the number of alternatives = 2 raised to the # of bits power. Two to the seventh power is 128

128-bit IP addresses
Interface ID
IPv6 address
128 Bits. An IPv6 address is made up of 8 fields consisting of 16 bits per field. If you multiply 8 x 16 will get 128 bits. Each field is separated by colons unlike IPv4 which was separated by dotted decimal notation. A good link to go to to see the address and how sub-netting is done is on the related links below.
The last 64 bits of an IPv6 IP address is called the Interface ID. These last 64 bits are used to uniquely identify an interface on the local link.
