Appendix C IP Addresses and Subnetting NBG334W User’s Guide 243 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 C IP Addresses a nd Subnetting NBG334W User’s Guide 244 Subnetting Y ou can use subnetting to divide one network into multiple sub-networks. In t h e 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 NBG334W User’s Guide 245 Figure 144 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).
Appendix C IP Addresses a nd Subnetting NBG334W User’s Guide 246 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.
