The Internet Corporation for Assigned Names and Numbers (ICANN) has added an IPv6 nameserver address to the Internet's DNS root server system, a move that promises to solve the possible shortage of IP addresses.

IPv6, or Internet Protocol next generation (IPng) , is designed to overcome the shortcomings of IPv4 by adding tightened security and improvements for routing and networking auto-configuration. IPv4 has been in use for almost 30 years and cannot support emerging requirements for address space, mobility and security in peer-to-peer networking.

With IPv6, which supports a 128-bit address space (instead of IPv4's 32-bit), the stage is set for many more devices to be uniquely addressed as the Internet continues to grow. It also expands into new types of devices that can be assigned with IP addresses, like telephones or even motor vehicles.

"By taking this significant step forward in the transition to IPv6, ICANN is supporting the innovations through which the Internet evolves to meet the growing needs of a global economy," the non-profit group said in a statement announcing IPv6 support.

In the beginning, IPv6 support will be implemented for Japan's (.JP) and Korea's (.KR) country codes. Next up, ICANN plans to implement the new protocol for France (.FR) before it approves other country codes.
