Tools for LARTing large nets of compromised boxen?

Thu Apr 20 06:51:35 UTC 2006

One of our customers is (has been) under concerted attempt at a DDoS attack 
against their web server off and on for a while.  I've lists of IPs, lots 
of them, many hundreds.  I'd like to know if anyone has a tool that will 
take and match these lists of IPs into abuse contacts and fire off a LART 
to the appropriate RP for the IP, but only one per full set, IE if RP-A has 
IP A.B.C.D and A.B.C.C he should get one mail clue-batting him for both IPs.

Any help?  TIA!
