Unit 3. Assignment 1. IPv6 Addressing
1a. 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. The Internet addresses must be unique and because address space on the Internet is limited, there is a need for some organization to control and allocate address number blocks. IP address management was formerly a responsibility of the Internet Assigned Numbers Authority (IANA), which contracted with Network Solutions Inc. for the actual services.
b. IANA (Internet Assigned Numbers Authority) is the organization under the Internet Architecture Board (IAB) of the Internet Society that, under a contract from the U.S. government, it has overseen the allocation of Internet Protocol addresses to Internet service providers (ISPs). IANA also has had responsibility for the registry for any for Internet operation.
c. The Asia Pacific Network Information Centre (APNIC) is an organization that manages the assignment of Internet number recourses within the Asian continent.
APNIC sets the rules, regulations and standards that all designated organizations must abide by and implement. End-user organizations and Internet service providers take direction from Regional Internet Registries (RIRs) like APNIC to provide Internet resources within certain regions.
2. Approximately how many IPv4 addresses are possible? There are approximately 4.3 billion addresses available. IPv4 address exhaustion is the exhaustion of the pool of unallocated Internet Protocol Version 4.
3. Approximately how many IPv6addresses are
