CIDR (Classless Inter-Domain Routing), or supernetting, is a way to allow more flexible allocation of IP addresses than was possible with the original system of 3 IP address classes (classes A, B, and C). The notation is something like: 192.168.1.0/26 (here the /26 is the key part, and it means that the first 26 bits are for the LAN, leaving the remaining 6 bits for the actual IPs of the hosts, so you can have 2^6=64 different IP addresses in your LAN)
