This document provides instructions for a lab assignment on subnetting and IP addressing. It outlines 8 steps to design an IP addressing scheme for a network with multiple subnets and router interfaces. The steps include determining subnet sizes, assigning subnet addresses, and allocating IP addresses to network device interfaces within each subnet.

NOTE: Record and highlight your results in this report based on the Packet Tracer Activity
instructions (which are the main source of instructions you should follow). Submit your Packet
Tracer source file separately with your submission (i.e., upload your PKA file to the BlackBoard
separately with this lab report). Failed to do so will result in mark deductions.
Task 1 Examine the network requirements
1. How many subnets are needed? ______
2. What is the maximum number of IP addresses that are needed for a single subnet? _____
3. How many IP addresses are needed for each of the R1 LANs? ______
4. How many IP addresses are needed for each of the R2 LANs? ______
5. How many IP addresses are needed for each of the R3 LANs? ______
6. How many IP addresses are needed for each of the WAN links between routers? ______
7. What is the total number of IP addresses that are needed? ______
8. What is the total number of IP addresses that are available in the 192.168.1.0/24 network?
______
9. Can the network addressing requirements be met using the 192.168.1.0/24 network? ______
Task 2 Design an IP addressing scheme
Step 1
Determine the subnet information for the largest network segment or segments.
a. How many IP addresses are needed for each LAN? ______
b. What is the smallest size subnet that can be used to meet this requirement? ____
c. What is the maximum number of IP addresses that can be assigned in this size subnet? _____
Step 2
Assign subnets to R1 LANs.
Fill in the chart below with the appropriate information. R1 LAN1 Subnet.

Step 3
Determine the subnet information for the next largest network segment or segments.
a. How many IP addresses are needed for each LAN? _____
b. What is the smallest size subnet that can be used to meet this requirement? _______
c. What is the maximum number of IP addresses that can be assigned in this size subnet? ______
Step 4
Assign subnet to R2 LANs. Start with the IP address following the R1 LAN subnets.
Fill in the chart below with the appropriate information. R2 LAN1 Subnet.

Step 5 Determine the subnet information for the next largest network segment or segments.
In this case, the two R3 LANs are the next largest subnets.
a. How many IP addresses are needed for each LAN? _______
b. What is the smallest size subnet that can be used to meet this requirement? _____
c. What is the maximum number of IP addresses that can be assigned in this size subnet? ______
Step 6
Assign subnets to R3 LANs.
Fill in the chart below with the appropriate information. R3 LAN1 Subnet.

Step 7
Determine the subnet information for the links between the routers.
a. How many IP addresses are needed for each link? ______
b. What is the smallest size subnet that can be used to meet this requirement? ______
c. What is the maximum number of IP addresses that can be assigned in this size subnet? ______
Step 8
Assign subnets to links. Start with the IP address following the R3 LAN subnets.
