inet hosts question

[Gary Hartl]

Hi all;

I have a quick question, I am trying to block a range of ip's for the sake
of example they are 192.168.0.0 - 192.168.255.255
For the life of me I can't remember how to do that.

I thought I could do it by using the /class ie /32 for class c but i can't
remember what the class delegation is for that size of pool, I think it is a
class B.

All help would be appreciated.

Cheers, 

Gary
