The subnet mask is used to determine what part of the IP address is the network ID. It is a 32-bit value that is used in conjunction with the IP address to identify the network and host portions of the address. The subnet mask is usually expressed in dotted decimal notation, and is often shown using the slash notation, which indicates the number of bits that are used for the network ID. For example, a subnet mask of 255.255.255.0 (or /24) indicates that the first 24 bits of the IP address represent the network ID, while the remaining 8 bits represent the host ID.
