subnetmMask
The subnet mask indicates which part of an IP address is
the network address and which the address of the comput-
er. The network address defines what is called the subnet.
Example 1
IP address:
192.168.178.247
Subnet mask:
255.255.255.0
The assignment of the first three groups of numerals in the sub-
net mask indicates that the first three groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.178.0
Address of the computer in the
subnet:
192.168.178.247
IP address pool in the subnet:
192.168.178.0 -
192.168.178.255
The IP addresses 192.168.178.0
and 192.168.178.255 are re-
served. This means that the ad-
dresses from 192.168.178.1 to
192.168.178.254 are available
for assignment to the comput-
ers.
Example 2
IP address:
192.,168.178.247
Subnet mask:
255.255.0.0
The assignment of the first two groups of numerals in the subnet
mask indicates that the first two groups of numerals in the IP ad-
dress define the network. The following addresses result:
