Unit 3 Assignment 1 IPv6 Addressing
1. Research the following organizations and explain their involvement with the Internet public IP addresses
a. American Registry for Internet Numbers (ARIN): ARIN manages the distribution of Internet number resources, including IPv4 and IPv6 address space and AS numbers.
b. Internet Assigned Numbers Authority (IANA): is a department of ICANN, a nonprofit private American corporation, which oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol-related symbols and numbers.
c. Asia-Pacific Network Information Center (APNIC): APNIC provides number resource allocation and registration services that support the global operation of the Internet.
2. Approximately how many IPv4 addresses are possible? 4.3 billion
3. Approximately how many IPv6 addresses are possible? 340 undecillion
4. Why do you think the world is running out of IPv4 addresses? The depletion of the pool of unallocated Internet Protocol Version 4 (IPv4) addresses. The world is running out of IPv4 addresses since people are increasing and the addresses are limited.
5. How long do you think it will take before the IPv4 addresses are completely exhausted? It could possibly become exhausted within the next two years or so.
6. Since IPv6 is the long-term solution for this issue, why do you think we are still using and assigning IPv4 addresses on the Internet? So that we can use up all off the addresses available on IPv4, therefore having more addresses free on IPv6.
7. Do you think the possibility exists for some companies to hoard IP addresses and not release them back to ARIN to turn a profit? Large organizations receive IP addresses in large blocks. Technically, unused numbers are supposed to be returned to ARIN. But the shortage could lead organizations to hoard those unused numbers and then try to profit by selling them to the
