## Using Examples

The tool includes interactive examples organized by category, making it easy to test different aspects of your network.

### Basic Connectivity

- `ping example.com` → Test basic connectivity to a website.
- `ping 8.8.8.8` → Test Google DNS for internet connection checks.
- `ping -c 20 example.com` → Run an extended ping test with 20 packets.

### DNS Lookup

- `nslookup example.com` → Perform a basic DNS lookup.
- `nslookup example.com 8.8.8.8` → Query using Google DNS.
- `nslookup -type=MX example.com` → Check mail server records.

### Network Path

- `traceroute example.com` → Trace the route to a website.
- `traceroute 8.8.8.8` → Trace the route to Google DNS.

### Detailed DNS

Use `dig` for comprehensive DNS queries:

- `dig example.com` → Full DNS information.
- `dig example.com MX` → Retrieve mail server records.
- `dig example.com NS` → View nameserver records.
- `dig @8.8.8.8 example.com` → Query a specific DNS server (Google DNS in this case).

## Domain Information

Use `whois` to check domain registration details:

- `whois example.com` → Displays registrar, registration/expiration dates, nameservers, and ownership info (if public).

### Using Examples

Interactive examples make it easy to get started:

1. Click any example command.
2. It will automatically populate the input box.
3. Modify it if needed (change domain, add options, etc.).
4. Click **Run Command** when ready.

## Latest Commands

The tool remembers your last five commands:
