Subnet mask topic

Subnet mask is also called network mask, address mask, and subnet mask. It is a bit mask used to indicate which bits of an IP address identify the subnet where the host is located, and which bits identify the host. The subnet mask cannot exist alone, it must be used in conjunction with the IP address. The subnet mask has only one function, which is to divide an IP address into two parts: the network address and the host address. A subnet mask is a 32-bit address that is used to mask a part of the IP address to distinguish the network identification and the host identification, and to indicate whether the IP address is on a local area network or a remote network.
