Your Computer Is Broadcasting an IP Address could become something of the past, or at least as private as the rest of your personal information in EU. This could have some fairly significant implications both technically and policy-wise for service providers. Since your IP address is likely unique except in a few rare cases (public wireless, hotels, conventions or maybe your office). If you have a cable modem, you’re likely to keep the same IP address for a long time. Some DSL providers you keep the same IP, others you can easily get a new one by rebooting the device. It should become interesting as time goes on and these personally identifying bits continue to proliferate. With IPv6, it may become easier to identify the user, or that it’s the same user, but we’re not there yet.
