2011 is the year that global allocations of the four billion, 32-bit IPv4 addresses are starting to run out. Although its replacement, IPv6, is a mature protocol, IPv6 deployment has been limited to date.
While there are as many IPv6 addresses as grains of sand in the world, the new protocol is not compatible with IPv4, so, during the protocol transition period—expected to last many years—new Internet users will be assigned both IPv4 and IPv6 addresses in a ‘dual stack’ arrangement.
On World IPv6 Day, June 8, 2011, major web companies globally and other industry players will enable IPv6 on their main websites for 24 hours. The goal is to motivate organisations across the industry—Internet service providers, hardware makers, operating system vendors and web companies—to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.
Internode leads Australia is its testing and adoption of IPv6. The company, which has worked on IPv6 adoption for a number of years, launched a public trial for its ADSL-based customers in November 2009.
Internode managing director Simon Hackett said World IPv6 Day was a chance to raise the profile of IPv6 in the service provider community. "Done right, consumers don't notice IPv6," he said.
"Internode has made sure our customers won't be disadvantaged through this large, significant change 'under the hood' of the Internet, and we welcome a chance to show our customers how seamless IPv6 is with Internode—even now, ahead of our official move to full production deployment later this year.
Internode welcomes World IPv6 Day as an opportunity to demonstrate what it has achieved with IPv6 and to encourage our peers in the Internet industry to explore and pursue IPv6 engagement as well."
