NBG-418N v2 User’s Guide 148 A PPENDIX A IP Addresses and Subnetting This appendix introduces IP addresses a nd subnet masks. IP addresses identify individual devices on a network. Ev ery networking device (including computers, servers, routers, printers, etc.
Appendix A IP Addresses and Subnetting NBG-418N v2 User’s Guide 149 F i g u r e 111 Network Number and Host ID How much of the IP address is the netw ork number and how much is the host ID v aries according to the subnet mask.
Appendix A IP Addre sses and Subnetting NBG-418N v2 User’s Guide 150 Subnet masks are expressed in dotted decimal nota tion 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.
Appendix A IP Addresses and Subnetting NBG-418N v2 User’s Guide 151 Subnetting Y ou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.
Appendix A IP Addre sses and Subnetting NBG-418N v2 User’s Guide 152 Figure 1 13 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits , so each sub-network has a maximum of 2 7 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’ s address itself , all ones is the subnet’ s broadcast address).
Appendix A IP Addresses and Subnetting NBG-418N v2 User’s Guide 153 Example: Eight Subnet s Similarly , use a 27-bit mask to create eight subn ets (000, 00 1, 010, 011, 100, 101, 110 and 11 1). The following table shows IP address last octet values for each subnet.

Appendix A IP Addresses and Subnetting NBG-418N v2 User’s Guide 155 Configuring IP Addresses Where you obtain your n etwork number depends on your particular situation. If the ISP or your network administrator assigns y ou a block of regist ered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
Appendix A IP Addre sses and Subnetting NBG-418N v2 User’s Guide 156 Conflicting Computer IP Addresses Example More than one device can not use the same I P address. In the following example computer A has a static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to computer B which is a DHCP client.
