Supernetting (CIDR) ChartCIDR – Classless Inter-Domain Routing. Note: The Number of Class C networks must be contiguous. For example, 192.169.1.0/22 represents the following block of addresses: 192.169.1.0, 192.169.2.0, 192.169.3.0 and 192.169.4.0.Class CCIDR BlockSupernet MaskNumber of Class...

The network administrator creates a 32-bit subnet mask composed of 1s and 0s. The 1s in the subnet mask represent the positions that refer to the network or subnet addresses. Not all networks need subnets, meaning they use the default subnet mask. This is basically the same as saying that...
