How is an IPv6 address structured?

• A. As four groups of three decimal digits
• B. As eight groups of four hexadecimal digits separated by colons
• C. As two groups of six binary digits
• D. As twelve decimal numbers in sequence

Answer: (B)

An IPv6 address is structured as eight groups of four hexadecimal digits, separated by colons. This design allows IPv6 to accommodate a significantly larger address space compared to its predecessor, IPv4. Each group of four hexadecimal digits represents 16 bits, and since there are a total of 128 bits in an IPv6 address, this results in a complete address framework that can represent an immense number of unique addresses. The use of hexadecimal notation is particularly efficient for IPv6 because it can compactly express the binary format used in IP addressing. Each hexadecimal digit corresponds to four binary digits (or bits), which makes it easier for humans to read and write compared to long strings of binary numbers. The separation by colons also aids in readability. The other answer choices do not align with the established structure of IPv6 addresses. For instance, four groups of three decimal digits would not provide the necessary bits required for a proper address, and two groups of six binary digits would only represent 12 bits, falling far short of the required 128 bits. Lastly, twelve decimal numbers in sequence would not conform to the hexadecimal structure employed in IPv6. Thus, the correct representation of an IPv6 address is indeed as eight groups of four hexadecimal digits separated by col
