Thanks Miles,
I don't know the users.

My cluster is located at South Korea but the requesting hosts are located at
Kansas(US).
( From utrace service, http://en.utrace.de/ )

Is there any other way to ban this request from my cluster ?

Even though I block 32.247.167.0~255, the same requests are repeated.
Is there the possibility of mis-configuration ?

Thanks.
