iBurst has successfully completed testing of IPv6 on its network (access, transmission, peering and transit), and will start enabling the packet gateways to use dual stack IPv4 and IPv6 from this week. The change will start in Gauteng, then Kwazulu-Natal and finally Western Cape.

iBurst’s Ronald Bartels explains that, after enabling IPv6 on its network, an iBurst subscriber with newer operating systems like Windows 8 or Windows 7 will receive both an IPv6 and IPv4 address.

“The operating system will try to reach a resource on IPv6 first and then fall back to IPv4 if not available on IPv6. As content sites move to IPv6 subscribers will automatically migrate,” explained Bartels.

Bartels added that anyone wishing to experience and experiment with IPv6 will be able to do so using an iBurst connection.

“We can also provide IPv6 over IPv4 tunnels. This will allow a person to buy an IPv6 kit that will allow then to use IPv6 from iBurst while obtaining legacy IPv4 from any ISP or mobile operator that hasn’t yet updated their technology.”

The biggest advantage of IPv6 is the larger number of available IP addresses, and here iBurst is also benefiting.

“We have billions of IPv6 addresses but less than half a million IPv4 addresses. It will reduce our reliance on IPv4,” said Bartels.

Bartels further highlighted that the IPv6 move will allow iBurst to establish a relationship with subscribers who are interested in IPv6 and who are the leaders in new technology adoption.
