Subnet masks play a crucial role in IP addressing by helping to efficiently allocate addresses and facilitate subnetting within a network. Understanding subnet masks is fundamental in computer networking as it allows for the segmentation of an IP address into two parts: the network address and the host address. This segmentation is essential for efficient
