In the context of computing and networking, masks are fundamental for defining which part of an IP address is used to identify the network and which part is used to identify hosts within that network. Masks are commonly represented in CIDR (Classless Inter-Domain Routing) notation, where the number of bits that make up the network part is indicated. For example, a subnet mask of 255.255.255.0 indicates that the first 24 bits of the IP address are the network part, while the last 8 bits are for hosts.
