American Registry for Internet Numbers (ARIN) is a nonprofit member-based organization who manages internet number resources throughout its designated service region. They coordinate the development of policies by the community for management of Internet Protocol number resources and advances the internet through informational outreach. They cover three areas and registration services is the area that deals with the allocation of IP address space, transfer and record maintenance. The Internet Assigned Number Authority (IANA) is one of the Internet’s oldest institutions with its activities dating back to the 1970’s. One specific task they have is to coordinate the global pool of IP and AS numbers providing them to Regional Internet Registries such as ARIN. The Asia Pacific Network Information Centre (APNIC) is an open, membership based, not-for-profit organization providing Internet addressing services to the Asia Pacific. The maximum number of potential IPv4 addresses is 4,294,967,926 and they are running out. IPv6 is being introduced to replace IPv4. There are potentially 340 trillion, 282 billion, 366 million, 920 thousand, 938 followed by 24 zeroes (also known as 2 to the power of 128) IPv6 addresses available. I think the world is running out of IPv4 addresses because almost everyone has one device or more that require an IP address. Also, some companies requested more IP addresses than they needed and they are sitting dormant waiting to be used. According to some estimates the IPv4 addresses will be depleted sometime within this year. Other estimates suggest 2037 as the year of depletion. APNIC ran out of IP addresses on 4/15/2011, IANA ran out of IP addresses on 2/3/2013 and a third estimate says that ARIN will run out on 3/22/2015. IPv6 has not gone mainstream yet because of Network Address Translation (NAT). NAT allows you
