Data protection people will have to learn how technology works and stop breaking IPv6 deployments with enforcing bad practices from IPv4 world. WE dynamically changed IPv4 address because we started running out of them, not to ensure anonimity. That warm fuzzy feeling is made-up collateral damage that was never even a intent ;) As Jordi mentioned, traceability starts on L7 and it doesn't matter how much you change addresses, you'll be trackable. For reference, try it on https://panopticlick.eff.org/ Click, change address, click again. > > And stable addresses are a way to make money. sys4 has a office in > Munich and VDSL from M-Net.
