As a follow-up to my previous post about turning off RFC4941 IPv6 temporary addresses, here are the instructions, tested with the current versions of the operating systems (OS X Mavericks, Ubuntu 13.10, Windows 8).

On OS X, run “sysctl -w net.inet6.ip6.use_tempaddr=0” to make an immediate change, and add “net.inet6.ip6.use_tempaddr=0” to /etc/sysctl.conf for a permanent change.

On Ubuntu, run “sysctl -w net.ipv6.conf.all.use_tempaddr=0” to make an immediate change, and add “net.ipv6.conf.all.use_tempaddr=0” to /etc/sysctl.conf for a permanent change.

On Windows, run the following and restart:
netsh interface ipv6 set privacy state=disabled store=active
netsh interface ipv6 set privacy state=disabled store=persistent
netsh interface ipv6 set global randomizeidentifiers=disabled store=active
netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
