Description
Subnet masks are used for splitting networks into
smaller networks called subnets. A subnet mask is a
32-bit binary number that splits the IP address into a
network address and host address.
Subnet masks are typically represented in either dotted
decimal notation or the more compact CIDR notation,
as shown in the table below.

Subnet mask in CIDR notation
IP gateways connect individual physical IP subnets
into a unified IP network. When an IP node needs to
communicate with an IP node on another subnet, the
IP node sends the data to the IP gateway for forward-
ing. Parameters 10...13
