When an IPv6 address is converted from hexadecimal into binary how many total binary digits are there?

IPv6 addresses are 128 bits long. In hexadecimal notation, there are 32 hex digits, and each hex digit represents 4 binary bits. So 32 × 4 = 128 binary digits in total. The standard form of an IPv6 address is eight groups of four hex digits, which reinforces that there are 32 hex digits and 128 bits. The other numbers would imply shorter lengths (256 bits would need 64 hex digits, 64 bits would need 16 hex digits, 32 bits would need 8 hex digits), which don’t match IPv6.
