You're saying that the chance it will try a duplicate IP again later is 0? Not quite 0... (1/(254*254))*3/8 + (1/(254*254*254))*4/8 =~ 0.00000584, or 0.000584%. Which means 1 out of about 171,144 generated numbers will be a dupe. I don't know what the average scan rate of this thing is, but if we assume 300 threads at 10 seconds each average to either deliver payload or time out, that's 95 minutes between dupes average. My logs also bear out that dupes are common. Ryan ---------------------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
