Explanation:
Detailed explanation-1: -An IPv4 address must contain three periods and four octets. The following examples are valid IPv4 addresses: 1 .
Detailed explanation-2: -The 32-bit IP address is grouped 8 bits at a time, each group of 8 bits is an octet. Each of the four octets are separated by a dot, and represented in decimal format, this is known as dotted decimal notation. Each bit in an octet has a binary weight (128, 64, 32, 16, 8, 4, 2, 1).
Detailed explanation-3: -There are four octets in an IPv4 address. Each address contains four numbers from 0 to 255 (one octet), separated by periods. As such, there are 4 bytes x 8 bits/byte = 32 bites in an IPv4 address. Therefore there are 2^32 = 4, 294, 967, 296 addresses.
