Get a box, and run Zebra BGPD, which will announce that /24 to your network.
Then do a script which monitors the traffic to the irc server, and on a
certain threshold, kill BGPD. wait a certain time, like 15minutes or so, and
restart BGPD. It would be nice to check the traffic every minute and if 2
consecutive checks are positive kill bgpd. That mean that you  may be able
to STOP dDoS to irc servers within 2-3 minutes...
