Surveying the State of IPv6 Deployment in Australia and China
IPv6 technologies used
For organisations that have deployed IPv6 (including those that have IPv6 deployed only in test environments) we asked about their IPv6 setup. Most organisation have a dual stack setup (58% Australia and 65% in China) whereas most of the remaining organisations use separate infrastructure for IPv6 (35% Australia and 30% China). A small minority (around 5%) has an IPv6-only setup.
Figure 3 shows the nature of an organisations IPv6 implementation (in percent for each country). A variety of approaches are used, such as auto-tunneling (e.g. 6to4, 6rd, ISATAP), translation technologies (e.g. NAT64, DNS64, XLAT) and static tunnel configurations. However, native IPv6 is the most common approach with dual-stack clients and servers. When comparing the two countries, in China almost 50% of organisations use Native IPv6 and there are fewer organisations that use tunnelling or translation.
