Which statement correctly describes IPv6 address length relative to IPv4?

Explanation:
The key idea is the difference in how long IPv6 addresses are compared to IPv4. IPv4 uses 32-bit addresses, which limits the number of unique addresses. IPv6 expands the address space to 128 bits, so the addresses are much longer and can represent vastly more devices. That makes the statement describing IPv6 as 128 bits and IPv4 as 32 bits the accurate description of their relative lengths. The other possibilities don’t fit: IPv6 is not shorter, not the same length, and it is not 256 bits. This longer address length is what supports the much larger address space IPv6 provides.
