Appendix C IP Addresses a nd Subnetting ES-3148 User’s Guide 328 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 C IP Addresses and Subnetting ES-3148 User’s Guide 329 Figure 209 Subnetting Example: Af ter 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).
