The maximum number of IPv4 addresses is:

IPv4 addresses are 32 bits long, so there are 2^32 possible unique addresses. That equals 4,294,967,296. This is the maximum number of distinct IPv4 addresses that can exist. In practice, some addresses are reserved for special uses, so the number of assignable addresses is slightly less, but the theoretical maximum is 2^32. The other options correspond to larger address spaces (such as IPv6) and don’t apply to IPv4.
