IPv6 has the power to change this paradigm since it becomes possible for every device to have a unique IP address. Though privacy extensions will help keep your device from being easily tracked, it is not without its own problems. The private connections have a limited duration so long term connections (movies, SSH, etc) will disconnect when the timeout is reached and a new session with a new temporary IPv6 address is used. Once the connection hits its max address limit, the privacy extensions are disabled and a traceable IP address is used.
