Ok, I know some of you guys are gonna think I am nuts but for some reason I can't get this. CIDR. I am trying to write a ruleset for my firewall. If I have an IP that is I know it is basically 192.168.*.*, and is 192.168.0.* but I don't get the or /32 etc subnets. I know the subnet for /22 is but what does that really mean in terms of IP address'?Can someone explain in plain English.
