What factors limit the number of available IPv4 addresses? (select all that apply)

1: The number of devices that connect to the Internet

2: How many people are downloading something at the same time

3: The number of public and private websites in existence

4:The number of IPv6 addresses in use

Answer: The correct option is 1 and 3.

Due to IPv4 (Internet Protocol version 4) address limitation by the 32-bit address space, we are making use of IPv6 addresses. While more devices are being connect to the Internet (option 1) and the number of public and private sites grows (option 3), the number of IPv4 addresses needed increase (option 2) thus depleting the pool of addresses (option 4). The total number of people downloading data simultaneously as well as the amount of IPv4 addresses in circulation will not directly influence the availability of the IPv4 addresses; they operate on separate protocols and address spaces. Besides, having the limited IPv4 address space was the fundamental constraint that served as a key aspect in the creation of the updated IPv6 protocol, which has a much more developed address space.
