But you have to also consider what your usage of DNS says about you. It is a treasure trove of data about your likes and opinions. Every time you click a link or type in an address in your browser you query a DNS server. This is usually the ones provided by your ISP when you connect to the Internet. It is also how you get served those custom search result error pages when a site does not exist.
