Unit 3 Assignment 1 IPV6 Addressing
1. Research the following organizations and explain their involvement with the internet public IP addresses.
* American Registry for internet Numbers (ARIN)
IP address space allocation & transfer and record maintenance.
Registration transaction information (WHOIS)
* Internet Assigned Numbers Authority (IANA)
IANA coordinates the global pool of IP and AS numbers. It provides the Regional Internet Registries.
* Asia-Pacific Network Information Center (APNIC)
APNIC allocates IPv4 & IPv6 address space.
Mantins the public Whois Database for the Asia Pacific region.
Also represents the interests of the Asia Pacific Internet community on the global stage.
2. Approximately how many IPv4 addresses are possible? 32 bit. About 4.294 Billion addresses.
3. Approximately how many IPv6 addresses are possible?128 bit. IPv6 can theoretically hold 2^128 IP addresses.
4. Why do you think the world is running out of IPv4 addresses? Because it is popular and there are many computers and cellphones, tablets all connected to a IP address.
5. How long do you think it will take before the IPv4 addresses are completely exhausted? I believe they have ran out already. Everything I read said that it should of ran out by 2012.
6. Since IPv6 is the long-term solution for this issue, why do you think we are still using the assigning IPv4 addresses on the internet? I think because it is trying to utilize the IP of IPv4 before they move on to IPv6 which has a lot of IP address spaces.
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? I think they might hold out for a profit. IP address is limited and people know they are running out so yes this seems logical.
