IPv6 addresses are larger than IPv4 addresses by what factor?

IPv6 addresses are larger than IPv4 addresses by what factor?

• A. Four times larger
• B. Twice as large
• C. Eight times larger
• D. The same size

Answer: (A)

IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses. To see how much larger IPv6 is, compare the lengths: 128 ÷ 32 = 4. So IPv6 addresses are four times as long as IPv4 addresses. Longer bit-length means far more unique addresses (2^128 versus 2^32), which is why IPv6 expands the address space.
