IPv4 foundations — tutor guide

Example three-session pack. Adapt goals and level to the actual learners before delivery.

Learning goals

Distinguish a host address from its network. Calculate broadcast, mask, usable host range and usable host count.

Suggested 30-minute session

1. 5 minutes: model the prefix and block size using one worked example.
2. 12 minutes: individual practice through the assignment link or worksheet.
3. 8 minutes: compare the method, not only the result.
4. 5 minutes: retry the most common mistake on a fresh address.

Marking rubric

One point for each of six values. Four problems = 24 points. Suggested formative bands: 20–24, progress; 14–19, targeted correction; 0–13, revisit prefix and block boundaries. These are teaching suggestions, not validated assessment standards.

Common misconceptions

• Host address used as network: locate the containing block.
• Broadcast used as last host: subtract one address.
• Host count includes reserved addresses: distinguish total from usable.
• Mask changed in the wrong octet: split prefix into complete octets plus remaining bits.
