By convention subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask followed by a continuous sequence of zeros for a total number of 32 bits Subnet masks can be referred to by the size of the network number part the bits with a 1 value For example an 8 bit mask means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes 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 Table 58 Subnet Masks BINARY 1ST 2ND 3RD 4TH DECIMAL OCTET OCTET OCTET OCTET 8 bit mask 11111111 00000000 00000000 00000000 255 0 0 0 16 bit 11111111 11111111 00000000 00000000 255 255 0 0 mask 24 bit 11111111 11111111 11111111 00000000 255 255 255 0 mask 29 bit 11111111 11111111 11111111 11111000 255 255 255 24 mask 8 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

IP addresses identify individual devices on a network Every networking device including computers servers routers printers etc needs an IP address to communicate across the network These networking devices are also known as hosts Subnet masks determine the maximum number of possible hosts on a network You can also use subnet masks to divide one network into multiple sub networks Introduction to IP Addresses One part of the IP address is the network number and the other part is the host ID In the same way that houses on a street share a common street name the hosts on a network share a common network number Similarly as each house has its own house number each host on the network has its own unique identifying number the host ID Routers use the network number to send packets to the correct network while the host ID determines to which host on the network the packets are delivered Structure An IP address is made up of four parts written in dotted decimal notation for example 192 168 1 1 Each of these four parts is known as an octet An octet is an eight digit binary number for example 11000000 which is 192 in decimal notation Therefore each octet has a possible range of 00000000 to 11111111 in binary or 0 to 255 in decimal ZyXEL NWA 1100 User s Guide Appendix G IP Addresses and Subnetting The following figure shows an example IP address in which the first three octets 192 168 1 are the networ
