Appendix A IP Addresses and Subnetting NBG-418N User’s Guide 149 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 I P Addresses and Subnetting NBG-418N User’s Guide 150 Subnetting Y ou can use subnetting to divide one network into multiple sub-networks. In the following e xample 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 Addresses and Subnetting NBG-418N User’s Guide 151 Figure 1 10 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 I P Addresses and Subnetting NBG-418N User’s Guide 152 Example: Eight Subnet s Similarly , use a 27-bit mask to create eight subn ets (000, 001, 010, 011, 100, 101, 110 and 11 1). The following table shows IP address last octet values for each subnet.
