From: Penang on
Can someone please tell me how to block a whole bunch of IP from a
certain ISP?

If I were to block a range of IP, from aaa.bbb.ccc.000 to aaa.bbb.ccc.
255 --- How would I do that?

I have heard about "HOSTS file" but I do not know how to block a whole
range of IP using that "HOSTS file" thing.

Can anyone please help?

Thank you !
