One result was a free software called Freegate, small enough to carry on a flash drive. It takes a surfer to an overseas server that changes I.P. addresses every second or so, too quickly for a government to block it, and then from there to a banned site. There's something I'm missing here. It seems to me that any server that changes its IP so frequently would: 1) Reveal reasonably quickly the full range of the IP pool from which it chooses those addresses. Therefore, it would be simple to ban the whole IP range. 2) Rely on dynamic DNS that has to be queried directly. Therefore, it would be simple to ban access that DNS server. I don't want to jump to conclusions, but if I'm not missing some crucial piece of information, this would mean that this "hacktivist" tool is merely being hyped by journalists who aren't tech-savvy.
