IPv4 address shortage reaching critical stage

Posted by ZDnet News
The shortage of IPv4 addresses has reached a critical stage, according to the registries that allocate internet numbers around the world.

The Number Resource Organization (NRO), which represents the registries, said on Tuesday that less than 10 percent of all IPv4 addresses remain available, threatening the future network operations of all businesses and organizations unless ISPs and businesses step up their migration to IPv6.

"The limited IPv4 addresses will not allow us enough resources to achieve the ambitions we all hold for global internet access," NRO chairman Axel Pawlik said in a statement on Tuesday. "The deployment of IPv6 is a key infrastructure development that will enable the network to support the billions of people and devices that will connect in the coming years."

However, where previous estimates had IPv4 addresses running out in 2011, it now appears addresses are more likely to be depleted in 2012, Pawlik told ZDNet UK. "That is based on the current growth rate, but there might be big allocation requests coming up — you never know," he said.
