The 6th June 2012 is World IPv6 day, where major internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.
Organized by the Internet Society, and building on the successful one-day World IPv6 Day event held on 8 June 2011, World IPv6 Launch represents a major milestone in the global deployment of IPv6. As the successor to the current Internet Protocol, IPv4, IPv6 is critical to the Internet’s continued growth as a platform for innovation and economic development.
Posilan are pleased to announce that we are taking part in World IPv6 day and that we started the adoption of IPv6, running alongside IPv4, on our core network a little over a month ago. Our main website, email and DNS is now IPv6 enabled, as is our VPS platform, dedicated servers and colocation . Other websites such as Facebook, Google and Bing are also commited to World IPv6 day.
What is IPv6?
Every machine on a network has a unique identifier. Just as you would address a letter to send by post, computers and other network devices use the unique identifier to send data to specific computers on a network.
Most networks today, including all computers on the Internet, use the TCP/IP protocol as the standard for how to communicate on the network. In the TCP/IP protocol, the unique identifier for a computer is called its IP address.
There are two standards for IP addresses – IP Version 4 (IPv4) and IP Version 6 (IPv6). The problem with IPv4 is that the world is rapidly running out of unique addresses to give out. In order to allow the Internet to continue, IPv6 has been created.
Whereas IPv4 allows just under 4.3 billion unique addresses, IPv6 allows approximately 3.4×1038 addresses (a massive number that we are unlikely to ever run out of again).
Posilan and IPv6
At the time of writing this article, our core services now are permanently available on IPv6 which includes our Website, MX, mail servers and core DNS servers. Our VPS platform is also IPv6 enabled and customers can request IPv4 and/or IPv6 addresses. Dedicated servers and co-locaton are also IPv6 ready
Later this year we plan to run tests with IPv6 to our WAN VPN before rolling it our to all client sites.
Our cPanel web hosting platform is not currently IPv6 enabled as the cPanel software is not yet compatible with IPv6, although it is planned and in development.
