Correct answer: B

The correct option is B (32).

An Internet Protocol version 4 (IPv4) address is a 32-bit numeric address used to uniquely identify a device on a network.

  • It is written in dotted-decimal notation, consisting of 4 octets (groups of 8 bits) separated by periods (e.g., 192.168.1.1).

  • Calculation: 4 octets x 8 bits/octet = 32 bits.

  • The total number of possible unique IPv4 addresses is 232, which is approximately 4.3 billion.
