 Appendix B IP Addresses and Subnetting

P-660N-T1A User’s Guide

273

The following figure shows the company network before subnetting.  

Figure 122   

Subnetting Example: Before Subnetting

You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into 
two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or 
/25).

The “borrowed” host ID bit can have a value of either 0 or 1, allowing two 
subnets; 192.168.1.0 /25 and 192.168.1.128 /25. 

The following figure shows the company network after subnetting. There are now 
two sub-networks, 

A

 and 

B

.
