A Correct answer
Explanation

IPv4 uses 32-bit addressing, allowing 2^32 unique addresses. This equals approximately 4.29 billion total addresses, which rounds to about 4.2 billion when accounting for reserved and private address ranges.

AI explanation

IPv4 uses 32-bit addresses, giving 2^32 ≈ 4.29 billion unique addresses in total — commonly rounded to roughly 4.2–4.3 billion in networking texts. Among the given options, 4.2 Billion is the closest to this actual figure; the other choices (5.8B, 6.4B, 3.2B) don't correspond to any standard IPv4 address-space calculation.
