CIDR addressing : csf.deny

[marks2013]

Hi Guys, My question is for clarification really.

1. To block by CIDR addressing do you enter it manually in to the csf.deny
2. I need to block a country / district.
180.254.50.81
180.254.24.22

180.246.47.79
180.246.55.220

There are a many more for each range but the format i'm looking at blocking is

180.254.x.x
180.246.x.x

Would this be the correct format at enter in to the csf.deny file.

180.254.0.0/16 # Spam
180.46.0.0/16 # Spam

I did read over the following information, but need clarification, where to enter the CIDR and How.

Topic ID =6&t=4203&hilit=cdir (Im unable to directly link to the topic (new member) link to the topic of reference).

Thank you in advance.

Are correct, that is the way of using CIDR in CSF.
