Show answer & explanation
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.
