Solution

With a 4-bit addressing protocol, you can have 2^4 unique addresses. This is because each bit can be either a 0 or a 1, so for 4 bits, you have 2 options for each bit, giving you a total of 222*2 = 16 unique addresses. Therefore, the Internet could support 16 devices, each with a unique address.

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?
