Example Eight Subnets
Similarly use a 27-bit mask to create eight subnets (000, 001, 010, 011, 100, 101, 110 and
111).
The following table shows class C IP address last octet values for each subnet.
Subnet Address: 192.168.1.64 Lowest Host ID: 192.168.1.65
Broadcast Address: 192.168.1.127 Highest Host ID: 192.168.1.126
