Step 1: Record the network address block
In the first column, record the address block used for the entire FilmCompany network chosen in the previous lab.
Step 2: Define the 254-host networks
Based on the requirements for the FilmCompany network, the address block is divided into twelve separate networks using four different masks.
In the second column of the table above, record the network blocks that will support 254 hosts per
network. In the last column, record the names of the networks that need to be assigned to these blocks.
The CIDR notation mask for the 254-host network is /24. What is the dotted decimal equivalent mask? _____ 255.255.255.0
Step 3: Define the 126-host networks
In the third column of the table above, choose the first unused 254 host address block to subdivide
into 126-host networks. In the last column, record the names of the networks assigned to these 126-host blocks.
The CIDR notation mask for the 126-host network is /25. What is the dotted decimal equivalent mask?
_____ 255.255.255.128
Step 4: Define the 62-host networks
In the fourth column of the table above, choose the first unused 126-host address block to subdivide
into 62-host networks.
In the last column, record the names of the networks assigned to these 62-host blocks.
The CIDR notation mask for the 62-host network is /26. What is the dotted decimal equivalent mask?
_____ 255.255.255.192
Step 5: Define the 14-host networks
In the fifth column of the table above, choose the first unused 62-host address block to subdivide into
14-host networks. In the last column, record the names of the networks assigned to these 14-host blocks.
The CIDR notation mask for the 14-host network is /28. What is the dotted decimal equivalent mask?
_____ 255.255.255.240
Task 2: Define the Host Address Assignments
For each network, determine and document the host addresses and broadcast addresses. Use the table
below to document these networks and host information.
Step 1: Record the network names and addresses in the addressing table
In the table below, record the network names for the FilmCompany in the first column and the corresponding network address in the second column.
Step 2: Calculate the lowest host address in the addressing table
The lowest address for a network is one greater than the address of the network. Therefore, to calculate the lowest host address, add a 1 to the network address. For each of these networks, calculate and record the lowest host address in the second column of the table.
Step 3: Calculate the broadcast address in the addressing table
The broadcast address uses the highest address in the network range. This is the address in which the bits in the host portion are all 1s. To calculate the broadcast for each of the networks listed, convert the last octet of the network address into binary. Then fill the remaining host bits with 1s. Finally, convert the binary back to decimal. For each of these networks, calculate and record the broadcast address in the last column.
Step 4: Calculate the highest host address in the addressing table
The highest address for each address is the network address is one less than the broadcast address for that network. Therefore, to calculate the highest host address, subtract a 1 from the broadcast address. For each of these networks, calculate and record the highest host address in the second column.
Network Names | Network Address | Lowest Host Address | Highest Host Address | Broadcast Address |

Web_access | 192.168.3.192 /28 | 192.168.3.193 | 192.168.3.206 | 192.168.3.207 |
default | 192.168.3.208 /28 | 192.168.3.209 | 192.168.3.222 | 192.168.3.223 |
management | 192.168.3.224 /28 | 192.168.3.225 | 192.168.3.238 | 192.168.3.239 |

Task 3: Examine Address Blocks for Overlapping Addresses
One of the major issues of planning network addresses is overlapping addresses. This is especially true when using VLSM addressing. Examine the table in the previous step to ensure that each network has a unique address range.
Are there any overlapping addresses in the networks? ___ Tidak
If there are any overlapping addresses, recalculate the addressing plan for the FilmCompany network.
