DDOS protection?

Now there are two ways - one manual, and one automatic. Obviously, the manual one is easiest and cheapest (generally free) and automatic really is you just buy a black box that manages pings and will recognize a DDoS attack and will just drop the relative IP packets. Now for manual, theres so many ways to protect yourself. One way is to have a secondary ip... like have you seen those ips like: randomip.no-ip.com? Those are generally free - and as long as no one knows your actual IP all you need to do is change the randomip.no-ip.com to something else, and bam no more link to the server and the DDoS reaches a dead end Another way is just to change your internal IP. Hope I helped.
