IPv6 addresses are true description.

• A. 256-bit address
• B. 64-bit address
• C. 32-bit address
• D. 128-bit address made up of eight 4-digit hexadecimal values

Answer: (D)

IPv6 uses 128-bit addresses, and they are typically written as eight groups of four hexadecimal digits separated by colons. This means eight 16-bit blocks, totaling 8 × 16 = 128 bits, which matches the description of a 128-bit address made up of eight 4-digit hexadecimal values. The other size claims don’t fit IPv6: 256-bit would be longer than standard IPv6, while 64-bit and 32-bit describe other addressing schemes and not IPv6. In practice, you might see a compressed form that reduces some zero groups, but the underlying length and eight-group structure remain 128 bits.
