Question

Why did we run out of addresses for the Internet? In the problems that follow, the number of different IP addresses that you can create with n bits is 2n.
a. An IP address using IPv4 uses 32 bits. Approximately how many different addresses can be represented by this standard? Given the large number of such addresses, why do you think the Internet ran out of them?
b. An IP address using IPv6 uses 128 bits. How many different addresses can be represented by this new standard? Do you think this is enough?
c. Telephone numbers in the United States or Canada use 10 digits. Why do you suppose we have not run out of telephone numbers yet?
