Suppose we used an Internet Addressing protocol that used 8 bits to encode a single address. With this protocol, how many devices would be able to have their own unique address?

• 64

• 256

• 16

• 128

• The ability to quickly translate domain names into IP addresses

• The ability for one device to have multiple IP addresses at the same time

• The ability to quickly locate an IP address within a large network

An IPv4 address has 32 bits. In anticipation of having more devices on the Internet than there are IPv4 addresses, we are currently in the process of switching to IPv6, which uses 128 bits to represent a single address. Which of the following best describes the result of using 128-bit addresses instead of 32-bit addresses?

• 2^96 times as many addresses can be represented

• 96^2 times as many addresses can be represented

• 2 times as many addresses can be represented
