Appendix B IP Subnetting

167

Since the mask is always a continuous number of ones beginning from the left, followed by a 
continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the 
number of ones instead of writing the value of each octet. This is usually specified by writing 
a “/” followed by the number of bits in the mask after the address. 

For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with mask 255.255.255.128. 

The following table shows all possible subnet masks for a class “C” address using both 
notations. 

Table 74

The first mask shown is the class “C” natural mask. Normally if no mask is specified it is 
understood that the natural mask is being used.

Example: Two Subnets

As an example, you have a class “C” address 192.168.1.0 with subnet mask of 255.255.255.0. 

Table 75

00000000

The first three octets of the address make up the network number (class “C”). You want to 
have two separate networks.

Divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits 
of the IP address to a network number bit. The “borrowed” host ID bit can be either “0” or “1” 
thus giving two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with 
mask 255.255.255.128.
