For a class B network, 128.1.2.3, the subnet mask 255.255.0.0 in default, in which the first two 
bytes are all 1s. This means more than 60 thousands of nodes in flat IP address will be at the 
same network. This is too large to manage practically. Now if we divide it into a smaller network 
by extending network prefix from 16 bits to, say 24 bits, its third byte is used to subnet this class 
B network. Now it has a subnet mask 255.255.255.0, in which each bit of the first three bytes is 
1. It’s now clear that the first two bytes is used to identify the class B network, the third byte is 
used to identify the subnet within this class B network and, of course, the last byte is the host 
number. 
 
Not all IP addresses are available in the sub-netted network.  Two special addresses are 
reserved. They are the addresses with all zero’s and all one’s. For example, an IP address 
128.1.2.128, what will the reserved IP address look like? All 0s mean the network itself, and all 
1s mean IP broadcast. 
 

 

 

 

 

 

 

 

 

 

 

 
In this diagram, the subnet mask with 25-bit long, 255.255.255.128, contains 126 members in 
the sub-netted network.  The length of network prefix equals the number of the bit with 1s in that 
subnet mask. With this, you can easily count the number of IP addresses matched. The 
following table shows the result. 

10000000.00000001.00000010.1 0000000
