And those privacy extensions prevent the provider of the IPs from knowing which prefix was given to which of their customers how? Plus, if you have multiple systems on your network, you would need to subdivide your space, and some data analysis could provide evidence that certain prefixes are being used by different systems with different users on them.

On other points mentioned, your DNS queries could give you away, even if you are using SSL. Also, if you are using SSL, if your browser does Server Name Indication, someone can still tell what site you're visiting, even if they can't see what you're accessing on that site.

If your ISP derives their primary income from the sale of advertising, they have a strong incentive to do whatever they need to do to see what you're doing in order to target ads at you.
