Other than that, you can limit the damage of a DoS attack if you employ the following multi-server setup: say you have 2 client servers ("leafs"), you run services (eg: anope), and all these servers are connected via a hub server. We call these servers irc1.test.net, irc2.test.net, services.test.net and hub.test.net. What you want to do is NEVER expose the true IP addresses of services and the hub. This way an attacker can never attack the machine. They can still attack irc1 & irc2 but not take down services or your entire network.
