Range Scout

Step 1: Load Targets

Use the app in full screen for a better view. This step is where you add the IPs or ranges you want to test. You can either paste targets directly or import them from a `.txt` file. The app accepts IPv4 CIDR ranges and single IPv4 addresses, and each target must be on a separate line.

1. Paste or Import

  This is the manual mode. Use it when you want to paste your own targets or import them from a file.

2. Operator list

  Select an operator only if you want to use `Automatic API Fetch`. If you are using your own list, you do not need to choose an operator.

3. Target Details

  This panel shows the current state and tells you what to do next. On this screen, it explains that no operator is selected yet and that manual target loading is available.

4. Load From

  This is where you choose how to load targets:

  - Paste Targets

  - Import TXT

  - Automatic API Fetch after selecting an operator

5. Notes and status

  This section explains the current loading rules. In this screenshot it shows that automatic API loading is locked until an operator is selected, and it reminds you that pasted targets must be entered one per line.

6. Paste Targets

  Click this to open the paste window. Paste one IPv4 address or one CIDR range per line.

7. Save Config

  Saves your current app settings and reuse for next sessions. This button is available in all steps.

8. Activity Log

  Shows recent actions, startup messages, and other app events.\

9. Status bar

  Shows quick help and navigation guidance at the bottom of the screen.

Important note

After you paste or import the targets and they are loaded successfully, press Scan Setup to start the DNS check and filter only the available IPs. `Scan Setup` is not visible in this screenshot because it appears only after targets are loaded.

Step 2: DNS Scan this step, we check the targets loaded in Step 1 and find the IPs that actually respond to DNS. After the scan is finished, you can export the working results and use them in any other scanner or tool to save time or continue with Range Scout Scanner.

1. Step Progress

  Shows which stage you are in: load targets, DNS scan, and DNSTT.

2. DNS Scan Details

  Explains what this step does and shows the current scan summary.

3. DNS Scan form

  Set scan options like workers, timeout, port, protocol, and DNSTT-related values.\

4. Pick Targets

  Choose which imported ranges or IPs you want to scan.

5. Start Scan 

  Starts the DNS check and filters the available IPs.

6. Export section

  After the scan completes, export the results. You can use the exported IPs in any other scanner.

7. Activity Log

  Shows recent actions and scan-related messages.

8. Status bar  

  Shows live help and current app status.

Once this step is finished, you can move to DNSTT Scan page. This option will become available only if you have finished scanning and you have good IPs in your scan list.

As mentioned before, you can export DNS result at this step and use this list in any other scanning tool to save time.

Step 3: DNSTT E2E

We only support DNSTT + Socks (no Auth)

This step tests the good DNS results from Step 2 with DNSTT. Only qualified resolvers are checked here.

If you leave DNSTT Pubkey empty, it does tunnel-only validation. If you set a pubkey, it also does full E2E validation.

1. Step Progress

  Shows that Load Targets and DNS Scan are done, and DNSTT is the current step.

2. DNSTT Details

  Explains what DNSTT does and shows the scan summary from the previous step.

3. DNSTT settings

  Set the domain, pubkey, timeout, score threshold, nearby IP option, and E2E URL.

4. Export settings

  Shows the export format, save scope, and output path for passed results.

5. DNSTT Results

  Shows how many candidates were found, how many were checked, and how many passed tunnel or E2E.

6. Start DNSTT

  Starts DNSTT testing on the qualified resolvers.

7. Export Passed / Copy Passed

  Export the passed IPs to a file or copy them to the clipboard for use in other tools.

8. Activity Log

  Shows DNSTT start, stop, cancel, and result messages.

9. Status bar

  Shows live status and short help messages.

How to use this step

1. Review the qualified resolvers from Step 2.

2. Enter your DNSTT Domain.

3. Add DNSTT Pubkey only if you want full E2E testing.

4. Click Start DNSTT.

5. After it finishes, use Export Passed or Copy Passed.
