I hear you there. I've noticed an upwards trend in dictionary attacks lately, so I wrote a script where I can attach a portion of a log file, specify the email address, the type of attack and send it off to the registered abuse email in just a click. It has sped up my process of reporting quite a bit.
Not that it matters, most ISP's seem to send them to /dev/null.
By Class C you mean a /24 right? So you are trying to block 126.96.36.199/24 ?
0.0.0.255, unfortunately, is not a class C's netmask. Aren't you blocking a lot more than just a class C with that netmask?
