Activity Overview: In this graded activity, students will determine subnet scopes, assess routing metrics and paths, identify aspects of ACL’s and Firewalls, and design an IPv4 address space.
Activity Outcomes: After completing this activity you should be able to
- Apply IP-Addressing conventions to subnet composition
- Identify ACL and Firewall rules, and their components
- Understand routing metrics and path determination
- Identify commonly used TCP/UDP ports (quiz)
Deliverable: Upload your answers to the items below as a .pdf export from the editor of your choosing. Then complete the external Lab 1.2.1 Knowledge Check.
Naming convention: “lastnamefirstinitial_L1.2.1.pdf” e.g: “smithp_L1.2.1.pdf”
Be sure to include your name, student number, and course (CNW-2511) at the top of your document.
Grading Rubric:
40% – Subnet Scope Exercises
30% – IP-Address Space Design
20% – Routing Metrics and Path-Determination Exercises

Subnet Scope Exercises
Determine the Network ID, Host Range, and Broadcast ID for the following IP Addresses:
You are REQUIRED to utilize an online subnet calculator of your choosing, here are two: ()
or
YOUR ANSWERS MUST BE SCREENSHOTS FROM THE OUTPUT OF YOUR CHOSEN CALCULATOR
IP-Address Space Design
You are REQUIRED to utilize an online subnet calculator () or
Create a subnet scheme that includes the following:
A) Subnet scheme that can fit 200 subnets with a minimum size of 1,024 IP’s using a Class A private address space (10.x.x.x)
B) Subnet scheme that can fit 80 subnets with a minimum size of 256 IP’s each, using a Class B private address space (172.16.x.x)
C) 3 (three) subnets for Router-to-Router connections using private Class C /30 address space (192.168.x.x.)
YOUR ANSWERS MUST BE DELIVERED AS SCREENSHOTS FROM THE SUBNET CALCULATOR OUTPUT (THERE WILL BE FIVE(5) TOTAL)

Routing Metric Exercise
Complete both sets of routing metric exercises below. The goal is to determine the path between each network with the lowest total “cost”. The metrics for each path are identified on each connecting line. See the example answer for possible formatting.
THERE ARE TWELVE(12) TOTAL ANSWERS FOR THIS SECTION OF THE ACTIVITY
Please refer to the Week 1 Part 1 Lecture recording if you have any questions.
- What is the most efficient path to take, based upon the metrics given? (Remember: the lower the metric, the more efficient the path, you can pass through networks to get to others)
- Network A – Network B
- Network A – Network C
- Network A – Network D
- Network B – Network C
- Network B – Network D
- Network C – Network D
Possible format “Router #(Total Path Cost)“:
“Network A – Network D: Router1(Total Cost 0), 2(1), 3(2), 5(4), 8(5), 10(6), Router11(Total Cost 8)”
So long as each path chosen is easily identified, formatting can be however the student deem fit. Students may screenshot the each diagram and trace out lines visually for each path (please color-code, or use a separate screenshot per path).
