Appendix D IP Addresses a nd Subnetting ES-305 User’s Guide 94 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 D IP Addresses and Subnetting ES-305 User’s Guide 95 Figure 61 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 D IP Addresses a nd Subnetting ES-305 User’s Guide 96 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.
