Surveying the State of IPv6 Deployment in Australia and China
Alternatives to IPv6
We also asked several questions that aimed to find out about the alternatives to IPv6: 1) obtaining more IPv4 addresses and 2) using NAT. Based on our survey 47% of Australian and 40% of Chinese organisations have purchased, directly or indirectly, IPv4 addresses from an IPv4 address broker or another company. Furthermore, 27% and 26% of Australian and Chinese organisations plan to buy IPv4 addresses in the near future and an additional 24% and 33% of Australian and Chinese organisations have no immediate plans to buy but are considering to possibly buy IPv4 addresses at some time in the future. This indicates that there is more demand for IPv4 addresses and we would expect to see further buying and selling of IPv4 addresses.
Of the Australian organisations 36% have NAT deployed, while 17% are trialling it and another 14% are planning to use it. Of the Chinese organisations only 30% have NAT deployed, but 25% are trialling it and another 25% are planning to it. The vast majority of organisations, 90% in Australia and 96% in China, that have NAT deployed, are trialling or planning for it, plan to use it along side IPv6. Figure 13 shows the NAT technologies considered by the organisations. No particular technology stands out and the differences between the two countries are small except for NAT64 where there is a significant difference.
