SterJo NetStalker Portable — Fast Network Scanner for USB Use

How to Use SterJo NetStalker Portable to Discover Devices on Your Network

What it is

SterJo NetStalker Portable is a lightweight, portable network scanner that finds devices on your local network, shows IP/MAC addresses, open ports, and basic device info without installation.

Preparation

1. Download the portable ZIP from the official SterJo site and extract to a USB or local folder.
2. Run the executable as administrator (recommended) to ensure full network access.
3. Ensure your PC is connected to the target local network (Wi‑Fi or Ethernet).

Step-by-step usage

1. Open SterJo NetStalker Portable (exe).
2. Select the network adapter to scan if more than one is listed.
3. Click the Scan (or Start Scan) button.
4. Wait for the scan to complete — results populate with discovered devices.
5. Review key columns: IP address, MAC address, device name (if detectable), open ports, and vendor.
6. Right-click a device for actions such as ping, open in browser (HTTP), copy details, or export results.
7. Use the Export/Save option to save scan results (CSV or text) for later review.

Interpreting results

• IP address: device’s network address.
• MAC address: hardware identifier; use vendor lookup to identify device manufacturer.
• Open ports: services the device is advertising; exercise caution before accessing ports.
• Device name: may be blank if the device doesn’t advertise a hostname.

Tips & best practices

• Scan during low network usage to reduce false negatives.
• Run repeated scans to spot new or transient devices.
• Cross-check unknown MAC vendors online to infer device types.
• Avoid scanning networks you don’t own or have permission to assess.
• Keep the portable app updated by checking the official site occasionally.

Limitations

• May not detect devices with strict firewall or stealth modes.
• Device details are limited compared with full-featured network management tools.

Quick troubleshooting

• No devices found: verify adapter selection and network connection; run as admin.
• Incomplete info: try scanning from a device on the same subnet as targets.
