OUR SUBNET PLANNING MISSION: We have been assigned an address of Assume 20 subnets are needed, with 5 hosts per subnet. Our mission is to identify each subnet address and the addresses of all hosts under each subnet.

Step 1. Convert the decimal dotted notation address to binary:

Step 2. Determine the Class of the IP Address : CLASS C

Step 3. Based on the Class, determine what part of the IP address is the network portion and what part of the address is the host portion: Network.Network.Network.Host

Step 4. Determine how many bits you need to borrow from the last octet (host portion) of the IP Address to give you the needed 20 subnets: 2 to the power of 2 = 4 subnets (less 2) 2 to the power of 3 = 8 subnets (less 2) 2 to the power of 4 = 16 subnets (less 2) 2 to the power of 5 = 32 subnets (less 2) 2 to the power of subnets (less 2)

Step 5. Since you borrowed five bits from the host for subnets, determine how many hosts can you have on each of those subnets? 2 to the power of 3 = 8 hosts (less 2) giving you 6 hosts per subnet.

Step 6. Determine the Binary Subnetworks Field Numbers (32 possible combinations): Subnet #Binary Subnetwork ……

Step 7. Determine the Range of Binary Host Field Numbers for Each Subnetwork: Subnet #Binary SubnetworkRange of Host #’s ……

Step 8. Determine Decimal Host Numbers for Each Subnetwork: Subnet #Binary SubnetworkRange of Host #’sDecimal Host Numbers ……

Step 9. Determine Our Subnet Addresses: # Binary SubnetworkRange of Host #’sDecimal Host #’sSubnet Address ……

Step 10. Determine Host Addresses of the Six Nodes of Each Subnet: # Subnetwork Range of Host #’s Decimal Host #’sSubnet Address Host Address Range thru thru thru ,222,5,33 thru thru thru thru thru thru thru thru thru ……

Step 11. Determine Broadcast Addresses of Each Subnet: Range of Decimal Subnet Host Broadcast # Subnetwork Host #’s Host #’s Address Address Range Address thru thru thru ,222,5,33 thru , thru thru thru thru thru thru thru thru ……

Step 12. Based on the Class, determine the subnet mask for network (remember that 5 bits were borrowed): Network Network Network Subnet Host

A data frame with a destination IP Address of would be used by the router, along with the submask of , to determine the correct subnet to switch the data to in the switching process: “ANDING” Process Performed by Router IP Address: Subnet Mask: Subnet: (Subnet in Decimal Dotted Notation: )
