FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -IP addresses are expressed as a set of four numbers-an example address might be 192.158.1.38. Each number in the set can range from 0 to 255. So, the full IP addressing range goes from 0.0.0.0 to 255.255.255.255. IP addresses are not random.

Detailed explanation-2: -To us, an IP address appears as four decimal numbers separated by periods. For example, you might use 204.132. 40.155 as an IP for some device in your network. You probably noticed that the four numbers making up an IP are always between 0 to 255.

Detailed explanation-3: -An IP address is a long string of numbers assigned to every device connected to a network that uses Internet Protocol as the medium for communication; it’s the digital world’s equivalent of the mailing address associated with your home or workplace.

Detailed explanation-4: -You can assign interfaces IP addresses that have different masks but the same network address if ANDed with the shortest mask. For example, 1.1. 1.1/16 and 1.1. 2.1/24 have the same network address 1.1.

Detailed explanation-5: -With IPv4, each address consists of four 8-digit binary numbers, called octets. An IPv4 address is 32 bits in total. The biggest number one can make with 8 regular digits is 99, 999, 999, but the biggest number one can make with 8 binary digits is 255 (11111111 in binary), so each octet can be any number from 0 to 255.
