I keep getting spam from greece and sri lanka.

I need to have these 2 ranges translated into the /16 or /9 or whatever for each. the subnets so i can toss the entire range.

Much thanks to those who can help me plz.

91.140.0.0 - 91.140.63.255
124.43.224.0 - 124.43.224.255

An online subnet calculator is your friend.

http://www.subnet-calculator.com/

91.140.0.0/18 for the first one...

I went to that site and entered the 2nd one , i think its /16 , if so thanks for teaching/showing me how to learn. (give a man a fish.he eats for a day , teach him to fish and he eat 4 eva, thanks bro)

If /16 is wrong that 124.43.224.0 - 124.43.224.255
then i may still be need help!

Er, no that's not right. Except for the part about teaching, yes, I was hoping to educate and help with an answer at the same time. I'll give you an even better URL: http://www.subnet-calculator.com/cidr.php

Put in 124.43.224.0 and see what CIDR mask you need. The CIDR mask is the number after the slash, e.g. /24.

thanks! that one is super helpful. I was able to block those ips and no more random sex chat emails , your great!

I wish there was a list i could drop into my deny_hosts of everything in the world IP ranges that are NOT USA. I could care less about email or anything from outside america on my server. :(___ __ ____

You might want to look into using RBL. It does a fantastic job filtering spam.
