09 SUBNET CIDR 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. 0

10 GW ADDRESS 1 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 forwarding. Parameters
10 … 13 define the four octets of the gateway
address.
