IPv6 Still Slow To Attract Support

We have had occasion in the past to lament the relatively low uptake of IPv6 to date, despite a growth in the number of connected devices. Analysis by Cisco suggests that this situation will improve somewhat in Australia, but even so less than half of all internet-connected devices worldwide will be IPv6-capable by 2017.

Data compiled for Cisco’s Visual Networking Index (VNI) (we covered some other figures from the study last week) suggests that in Australia there will be 124 million total IPV6 connected-devices in 2017, up from 17 million in 2012, and 85 per cent of connected devices will be IPv6-capable. That will be something of an anomaly in global terms, where the numbers are much lower:

Note that the chart covers devices capable of using IPv6, which doesn’t necessarily mean they will use it. Many carriers use network address translation (NAT) to share IPv4 addresses amongst a larger group of devices, and that behaviour shows little sign of stopping.
