Overview
Module: Module 1: Infrastructure & Addressing
Activity type: Homework / independent application
Bloom move: push from guided practice into independent Apply/Analyze
Objective: Given a host, the learner can read IPv4 address, mask, and gateway; explain network vs host bits; contrast classful charts with classless /24 math; and decide same-LAN vs via-gateway delivery.

Complete without peeking at lab hints first. Then compare.
In plain words: Big idea: Complete **without** peeking at lab hints first.

Independent practice
In plain words: You do: close the hints. Struggle is part of learning.
You do: close the hints. Solve before opening the lab.
In plain words: Big idea: **You do**: close the hints.
On your lab host, record IP, mask, gateway. Compute usable hosts for your /24 (or explain your real mask). Explain loopback in one sentence.
In plain words: Loopback talks only to this computer. Ping 127.0.0.1 to check the local IP stack.

Application task
In plain words: Read this block, then try the next action. If you feel stuck, tap What this means.
- Restate the learning objective as a checklist you can tick with evidence.
- Produce the build output for this topic: find your host’s IPv4, mask, and gateway; explain network vs host bits with the “255 / 0” reading hack; map an address to its historic class (A–E) and default mask; calculate usable addresses on a simple
/24; prove same-LAN vs via-gateway reachability; prove loopback withping 127.0.0.1 - Attach workbook evidence (commands, redacted screenshots, tables).
- Write three spiral connections: how this topic uses an earlier skill, and where a later module will reuse it.
In plain words: An IP address is how devices find each other on a network. The mask tells which part is the ‘street’ and which part is the ‘house number.’
