One would think just reassigning the IP address quickly or setting up a backup network would do the trick. Seriously though, how can some small group's computers possibly overwhelm a massive network's system, even with a DOS attack? One would think no matter how much they try, the number of simultaneous connections they could muster would pale in comparison to what Sony's routers could handle and deny. I mean, how about something as simple as refusing to even open a connection with any IP address that makes a certain number of failed connection attempts in a specific amount of time?Most modern DOS attacks come from BOTNets which are made up of millions and millions of zombie computers.. So where are not talking about a small group here. And a backup network, while it's a good idea, really isn't feasible.. You might be able reassign DNS so the playstations look for service at a different IP, but playstation wouldn't be able to change their ip all that easily, it would require a change from there telcom provider.. One option is to have a backup network ready to go from a supernet of IP addresses but even still that dosn't stop the attack on the existing network.
