I just read about a potential privacy issue with IPv6 addresses on phones. While the article mainly talks about Apple devices, Android is mentioned so I wonder:

Does Android support IPv6 privacy extensions and how can they be enabled/disabled?

According to this question, Android currently has partial support for IPv6.

Interesting question. I'm wondering how the problem noted in the article is actually a real concern, though. –  Matthew Read Jan 14 '11 at 20:12
    
@MatthewRead When the EUI-64 address is used, the IPv6 address becomes (in theory) unique to the device. It identifies the device and possibly the manufacturer (of the NIC, at least). Though, so does the User-Agent string, and nobody cares much about those because they don't necessarily uniquely identify the device. –  Michael Hampton Apr 29 '13 at 4:09

If your device is rooted go to the terminal after each boot and enter
sysctl -w net.ipv6.conf.default.use_tempaddr=2
sysctl -w net.ipv6.conf.all.use_tempaddr=2

For automatic activation you could also add these lines to /etc/sysctl.conf
net.ipv6.conf.all.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2

Isn't there an app for that? –  Robert Jan 18 '11 at 19:11
    
Not yet. ;-) Seriously I don't think this is worth an app. it is merly a setting that should be configurable in the Wireless settings window. –  torusJKL Jan 20 '11 at 11:34
