how the internet works
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?
256
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

Two different devices, built by different manufacturers, and running software built by different companies, are both connected to the Internet. Which of the following best describes the ability of the two computers to communicate with each other across the Internet?
