ARIN Finally Runs Out of IPv4 Addresses
In the next week, the American Registry for Internet Numbers (ARIN) will have exhausted their supply of IPv4 addresses. The metaphorical IPv4 cupboards are bare. The Internet will continue to operate, but all organizations must now accelerate their efforts to deploy IPv6. At this point, the rules for how IPv4 address resources are allocated will change. Request might not get fulfilled and applicants might be offered a smaller block or the choice to be added to a waiting list for IPv4 addresses that become available.
As the Internet began to grow, techniques like Classless Interdomain Routing (CIDR) and Network Address Translation (NAT) were used to extended life-support for IPv4 for almost two decades. Some enterprise organizations still have not given IPv6 much thought and are not aggressively moving to implementing it. They are playing a dangerous "game of chicken" by ignoring IPv6. Internet Service Providers (ISPs) should already be well on their way through their IPv6 deployments, or are in serious danger of falling far behind competitors.
