Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An IPv4 address has 32 bits, so there are 232 (over 4 billion) possible IPv4 addresses. Since the Internet is gaining devices quickly, we will soon surpass 232 unique devices on the Internet.In anticipation of all the new Internet devices, we are in the process of switching to IPv6, which uses 128 bits for a single address. That’s 96 extra bits to represent one address!Which of the following statements correctly describes how many more addresses will be possible to represent by switching from IPv4 to IPv6?
A
96 more addresses can be represented with IPv6
B
296 more addresses can be represented with IPv6
C
96 times as many addresses can be represented with IPv6
D
296 times as many addresses can be represented with IPv6
Explanation: 

Detailed explanation-1: -Which of the following best describes whether these two computers can communicate with each other across the Internet? The computers can communicate directly because Internet communication uses standard protocols that are used by all computers on the Internet.

Detailed explanation-2: -Which of the following is a benefit of the fault-tolerant nature of Internet routing? The ability to use multiple protocols such as hypertext transfer protocol (HTTP), Internet protocol (IP), and simple mail transfer protocol (SMTP) to transfer data.

Detailed explanation-3: -IPv6 uses 128-bit addresses as opposed to the 32-bit addresses used by IPv4, allowing for a substantially larger number of possible addresses. With each bit corresponding to a ‘0’ or ‘1’, this theoretically allows 2^128 combinations or 340 trillion, trillion, trillion addresses.
