GS-1524/GS- 1548 User’s Guide 149 A PPENDIX A IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify ind ividual devices on a network. Every networking device (includin g computers, servers, routers, printe rs, etc.
Appendix A IP Addre sses and Subnetting GS-1524/GS-1548 User’s Guide 150 Figure 89 Network Num ber and H ost ID How much of the IP address is the network number and how much is the host ID varies according to the s ubnet mask.
Appendix A IP Addresses and Subnetting GS-1524/GS- 1548 User’s Guide 151 Subnet masks are expressed in dotted decimal no tation just like IP addresses. The follow ing examples show the binary and decimal not ation for 8-bit, 16-bit, 24-bit an d 29-bit subnet masks.
Appendix A IP Addre sses and Subnetting GS-1524/GS-1548 User’s Guide 152 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 c ompany network for security reasons.
Appendix A IP Addresses and Subnetting GS-1524/GS- 1548 User’s Guide 153 Figure 91 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 Addre sses and Subnetting GS-1524/GS-1548 User’s Guide 154 Example: Eight Subnet s Similarly , use a 27-bit mask to create eight subnets (000, 00 1, 010, 01 1, 100, 101, 1 10 and 111 ) . The following table shows IP address last octet values for each subnet.
Appendix A IP Addresses and Subnetting GS-1524/GS- 1548 User’s Guide 155 Subnet Planning The following table is a summary for su bnet planning on a network with a 24-bit network number . The following table is a summary for su bnet planning on a network with a 16-bit network number .
Appendix A IP Addre sses and Subnetting GS-1524/GS-1548 User’s Guide 156 Configuring IP Addresses Where you obtain your netwo rk number depends on yo ur particular situation. If the ISP or your network administrator assigns yo u a bloc k of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.
