In computer networks, each machine is identified through its IP (Internet Protocol) address, which is unique within a network. An address following IPv4 standards has 4 octets separated by dots. An example of an IPv4 address is 192.168.0.1. The octets of this IP address range from 0 to 255, which essentially means that each octet can represent 256 values. The IP addresses are classified into 5 types, and the following table depicts the range of IP addresses each class supports:

What is the size of the total address space of IPv4, i.e. the number of valid IPv4 addresses? A. 2^31 B. 2^32 C. 2^32 - 1 D. 2^33 - 1 Question 2 If every one of the roughly 8 billion people on Earth wanted to have a networked device with their own, unique IPv4 address, would there be enough IPv4 addresses? A. Yes B. No Question 3 An IPv4 subnet is a network inside the larger network, identified by a certain number of initial bits that are common to all the addresses in the subnet. The number of common bits (aka the prefix length) is given with a slash after the base address (i.e. the lowest address) of the subnet. The remaining bits are available to be freely assigned to hosts in the subnet, with the exception that the base address is reserved for the subnet number, and the last address is reserved for the subnet broadcast address. These two addresses are still part of the subnet. For example, the routing prefix 192.168.1.0/24 defines a subnet with a constant first 24 bits, i.e. with a prefix length of 24. Available host addresses in this subnet are 192.168.1.1 to 192.168.1.254. 192.168.1.0 is the subnet number; 192.168.1.255 is the broadcast address. There are 256 addresses in this subnet, and 254 available host addresses. How many available host addresses are there in the subnet 10.0.0.0/8? Enter the answer as a decimal number.
Given that the IPv 4 internet address of a computer interface is either Class A, Class B, or Class C, how many IPv4 Internet addresses are available?
