SY0-301 · Question #632
Which of the following protocols allows for the LARGEST address space?
The correct answer is C. IPv6. IPv6 uses 128-bit addresses, providing a vastly larger address space than all other listed protocols, which use far fewer bits.

Why each option
IPv6 uses 128-bit addresses, providing a vastly larger address space than all other listed protocols, which use far fewer bits.
IPX uses 80-bit addressing (32-bit network + 48-bit node), which is smaller than IPv6's 128-bit space.
IPv4 uses 32-bit addresses, providing roughly 4.3 billion addresses, far fewer than IPv6.
IPv6 uses 128-bit addresses, yielding approximately 3.4x10^38 unique addresses. This is orders of magnitude larger than IPv4's 32-bit space (~4.3 billion addresses) and far exceeds the address spaces of legacy protocols like IPX and AppleTalk. The 128-bit design was specifically created to solve IPv4 address exhaustion.
AppleTalk uses a 16-bit network and 8-bit node address scheme, giving it an extremely limited address space compared to IPv6.
