"The u.s. under the control of the treasury department controls the root dns servers. these servers control how every server in the world would be able to see the server your running. Example: thepiratebay.org redirects to an IP address say 192.168.1.1(example). If this law is passed and they decided to shut it down, one they would redirect thepiratebay.org to riaa.org(as an example). they would do that at the root level, and it would pass down to every server in the world. Second, they would order the company providing service to the website to return the IP to themselves, or face having there scope pulled. that would mean that the ISP would be forced to turn off the IP that they provide to the website. Once thats done, the site ceases to be. If you cant get to it via name, and you cant get to it except maybe through a dynamic IP on a cable modem, chances are it will go away. Additionally there are only a limited number of providers for a given area, and once you burn through them, you will be forced to go offline. doesnt matter whether you want to or not."
