The supply of IPv4 addresses has become depleted as more devices connect to the Internet. The need for more IP addresses has increased and is driving the transition to IPv6. Despite several attempts to generate global awareness (IPv6 day in 2011) and encourage action (IPv6 mandate in June 2012), the adoption rate and readiness to adopt IPv6 has only increased slowly.
In 2012, Curtin University surveyed the top 180 IT users within corporations, state and federal government departments and not-for-profit organisations in Australia on the transition to IPv6. This research uncovered high awareness of IPv6, with 91% of respondents having heard of the term before the survey. But alarmingly only 27% believed the transition to IPv6 to be urgent, with 52% asserting that it was not urgent. Essentially, more than half of those surveyed are unprepared for IPv6.
Over a year has passed since this research and not much has changed in Australia. The Cisco IPv6 Lab recently generated a report on global IPv6 adoption based on public research and Cisco’statistics. The table below outlines the top 20 countries with highest IPv6 readiness.

The top five are made up of Switzerland, Romania, Luxembourg, France and Germany. Australia fails to make the top 20, and comes in at number 22, with a relative readiness score of 3.1. Australia’s IPv6 deployment level - made up of three separate variables - the IPv6 prefix, the Transit AS and web content - is at 19.36%, which is significantly lower than the other countries on the list.
Peter Dell uncovered the main reasons for low IPv6 adoption in a survey by Curtin University.
Those who choose to rely on NAT, according to Dell, will face a set of problems as NAT imposes constraints on the services that can be offered to the internet, and does not scale well, disrupting the business and ultimately driving up the ownership cost of a network.
So with the rapid exhaustion of IPv4 addresses, Dell suggests that the low readiness level will cause a significant problem for Australia’s Information and Communications Technology industry, where organisations will be obliged to deploy IPv6 without proper planning, understanding or training.
Businesses may be backed into a corner when IPv4 addresses run out, and as a last resort, be forced to develop ad-hoc network intermediation devices that attempt to close the gap of a broken end-to-end network architecture, which could only result in chaos in their network.
