CIDR stands for Classless Independent Domain Routing. It replaced Classes A, B, C networks on the Internet. The CIDR notation counts how many left-most bits are contained in a netmask. So that a class A would be a /8, a class B would be a /16 and a class C would be a /24. A /32 is an individual IP and /0 represents the entire Internet often used with firewalling.
