Are IPv6 Privacy Extensions supported and how can they be enabled/disabled? 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.
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
