Free proxy list

If you are looking to see a gambling site at work or any site where you do not want to be tracked or you can't access, try a free proxy. Anonymous proxy servers hide your IP address and thereby prevent your from unauthorized access to your computer through the Internet. They do not provide anyone with your IP address and effectively hide any information about you and your reading interests. Besides that, they don't even let someone know you are surfing through a proxy server.
