There's nothing "indiscriminate" about it.I often block /24's and larger because I'm holding the *network* operators responsible for what comes out of their operation.

I don't care why it happens -- they should have thought through all this BEFORE plugging themselves in and planned accordingly. ("Never build something you can't control.")I would have to respectfully disagree with you. When network operators do due diligence and SWIP their sub-allocations, they (the sub-allocations) should be authoritative in regards to things like RBLs. $.02,
Yes. But the answer is that it also depends how many other cases like this exist from same operator. If they have 16 suballocations in /24 but say 5 of them are spewing, I'd block /24 (or larger) ISP block. The exact % of bad blocks (i.e. when to start blocking ISP) depends on your point of view and history with that ISP but most in fact do held ISPs partially responsible. -- William Leibzon Elan Networks [EMAIL PROTECTED]
