 Appendix G IP Addresses and Subnetting

ZyXEL NWA-3100 User’s Guide

269

Subnet masks are expressed in dotted decimal notation just like IP addresses. The following 
examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet 
masks. 

Network Size

The size of the network number determines the maximum number of possible hosts you can 
have on your network. The larger the number of network number bits, the smaller the number 
of remaining host ID bits. 
An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 
24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast 
address for that network  (192.168.1.255 with a 24-bit subnet mask, for example).
As these two IP addresses cannot be used for individual hosts, calculate the maximum number 
of possible hosts in a network as follows:

Notation

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 subnet mask 
255.255.255.128. 
The following table shows some possible subnet masks using both notations.
