# Lab OS-7: Windows Networking

Domain:
- 1.0 Operating Systems

Works on:
- Windows
- Linux comparison practice

Does not require:
- macOS

## Goal

Practice basic network identification and map common network scenarios to the right Windows settings.

## Windows Steps

Run:

```powershell
ipconfig
ipconfig /all
ping 127.0.0.1
nslookup example.com
net use
ncpa.cpl
firewall.cpl
```

Record:
- IPv4 address:
- Subnet mask:
- Default gateway:
- DNS server:
- DHCP enabled:
- Network adapter name:
- Any mapped drives:
- Current firewall profiles visible:

Scenario matching:
- Need to map `H:` to `\\server\share`:
- Need to remove mapped drive `H:`:
- Need to change DNS manually:
- Need to allow an app through firewall:
- Need stricter settings on public Wi-Fi:
- Need to reduce data usage on a hotspot:

## Linux Comparison Steps

Run:

```bash
ip addr
ip route
cat /etc/resolv.conf
ping -c 4 127.0.0.1
```

Record:
- IP address:
- Default gateway:
- DNS server:
- Loopback test successful:

## What You Should Learn

- `ipconfig /all` gives detailed Windows network settings.
- `169.254.x.x` usually means DHCP failed and APIPA was assigned.
- `net use` displays or maps network drives.
- `ncpa.cpl` opens adapter settings.
- `firewall.cpl` opens Windows Defender Firewall.
- Public network profile is stricter than Private.
