1. Research the following organizations and explain their involvement with the internet public IP addresses. A. American Registry for Internet Numbers (ARIN)
The American Registry for Internet Numbers (ARIN) is the nonprofit corporation responsible for managing Internet number resources (IPv4 and IPv6 addresses and Autonomous System Numbers) for Canada, many Caribbean and North Atlantic islands and the United States. B. Internet Assigned Numbers Authority (IANA)
IANA delegates allocations of IP address blocks to Regional Internet Registries (RIRs). Each RIR allocates addresses for a different area of the world. Collectively the RIRs have created the Number Resource Organization formed as a body to represent their collective interests and ensure that policy statements are coordinated globally. The RIRs divide their allocated address pools into smaller blocks and delegate them in their respective operating regions to Internet service providers and other organizations. Since the introduction of the CIDR system, IANA typically allocates address space in the size of /8 prefix blocks for IPv4 and /23 to /12 prefix blocks from the 2000::/3 IPv6 block to requesting regional registries as needed. C. Asia-Pacific Network Information Center (APNIC)
In April 2011, APNIC became the first Regional Internet Registry to run down to its last /8 block of IPv4 addresses, thus triggering the final phase of its IPv4 exhaustion policy. As a result, APNIC has now implemented a rationing policy for allocating the last /8 to its users, in which each APNIC customer will be eligible for just one final maximum allocation of a /22 block of IPv4 addresses until the block is exhausted. 2. Approximately how many Ipv4 addresses are possible?
IPv4 provides approximately 4.3 billion addresses.
3. Approximately how many Ipv6 addresses are possible?
.4X10^38 (18 quintillion) possible unique addresses
4. Why do you think the world is running out of IPv4 addresses? Because of all the new...
