Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. If you don't subnet, you will only be able to use one network from your Class A, B, or C network. Unless you have been assigned many major networks, you really need to subnet.
Each data link on a network must be a unique subnet, with every node on that link being a member of the same subnet. For serial interfaces (standard HDLC), you will need one subnet for the circuit, or "wire" (both ends of the serial connection will be in the same subnet). If you are planning on implementing Frame Relay, SMDS, X.25 etc, read the Router Products Configuration and Reference Guides for assistance in configuring.
A subnet mask is defined for each IP address. The subnet mask identifies which portion of the 4 octets is used to identify the data link, with the remaining bits identifying the node. If you want no subnetting, use these......
