One, Core Interface and Work Area Details
After launching IP Scanner Pro, the main interface is divided into several functional areas:
- Toolbar: Located at the top of the window, containing core operation buttons such as start/stop scanning, setting scanning range, and choosing scanning mode. These buttons follow the macOS Human Interface Guidelines, providing a smooth and intuitive user experience.
- Scan Range/Target Input Area: Below the toolbar, used for inputting the IP address range to be scanned (e.g.,
192.168.1.1-254) or subnet (e.g., 192.168.1.0/24). The input box supports auto-complete and history records, making it very user-friendly.
- Main Result List: Occupying the center of the window, displaying all discovered devices in a table format. The default columns include:
- IP Address: The network address of the device.
- Status: Online (green circle) or offline.
- Hostname: The network name of the device.
- MAC Address: The physical address of the device.
- Vendor: The manufacturer of the device identified by the first few bytes of the MAC address.
- Response Time: The delay when the device responds to the scan.
- Details Panel: Usually located at the bottom or side of the window. Clicking on any device in the result list will display more detailed information about that device, such as open ports, NetBIOS information, Bonjour services, etc. This design follows the Finder’s preview panel logic, making it easy to use.
- Filter and Search Box: Located above the result list, used for quickly filtering online devices, specific vendor devices, or searching by keywords. Combined with macOS’s native “Focus Search” shortcut key, it can quickly locate the target.
Two, Complete Operation Flow: From Scan to Export
1. Create/Configure Scan Tasks
Operation Steps:
- Define Scan Range: In the “Scan Range” input box below the toolbar, input the target IP range. Common formats include:
- Single IP:
192.168.1.105
- IP segment:
192.168.1.1-192.168.1.254 or 192.168.1.1-254 (simplified format)
- CIDR subnet:
192.168.1.0/24
Please note that if you are unsure about your computer’s IP segment, you can check the details of the current network connection in “System Settings -> Network”. This is the first step to avoid “scanning devices that are not found”.
- (Optional) Choose Scan Mode: Click on the “Mode” dropdown menu in the toolbar to select:
- Quick Scan: A quick Ping scan to detect whether the device is online. Suitable for scenarios where you need to quickly understand the number of active devices in the network.
- Deep Scan: A deep scan to obtain detailed information such as hostnames, MAC addresses, vendors, and open ports. This is the most frequently used mode in daily use.
The default mode is “Deep Scan” to obtain comprehensive information.
2. Execute Scan
Operation Steps:
- Click on the “Start Scan” button (green circular play icon) in the toolbar or press the shortcut key
Command + R. You will hear a slight “ding” sound, indicating that the scan has started. This is a common feedback mechanism for macOS applications.
- The scan progress will be displayed at the bottom of the window. The result list will be refreshed in real-time, adding new discovered devices row by row. For large networks (such as over 254 IP addresses), it is recommended to use “Quick Scan” to preliminarily understand the active devices.
- To stop the scan, click on the “Stop Scan” button (red) or press the shortcut key
Command + . (period). After stopping, all the information scanned before will still be retained.
3. View and Analyze Results
Operation Steps:
- In the result list, click on any device row to select it. The selected row will be highlighted with a slight animation transition.
- View the details panel to obtain more detailed information about the device, such as open ports, shared folders (if the related scanning module is enabled), and services. These information are crucial for troubleshooting network conflicts or discovering unauthorized devices.
- Use the filter at the top of the list, such as clicking “Alive” to filter out all online devices. You can also combine multiple filter conditions, such as filtering out devices that are “online and have a MAC address vendor of Apple.”
- Right-click on any device in the list to use the context menu for quick operations, such as “Ping,” “Traceroute,” or “Open in Browser” (for HTTP services). These features simplify the maintenance process without switching to the terminal.
4. Export Scan Results
Steps:
- Ensure that the scan results you need are available.
- Click the menu bar File → Export… or use the shortcut
Command + E. A dialog will prompt you to choose the export format.
- In the save dialog box, select the export format (typically supports CSV, TXT, XML). CSV is the most universal format and can be directly opened with Excel or Numbers for further analysis.
- Select the save location, name the file, and click “Save”. It is recommended to include the scan date in the file name, such as “Network_Scan_2025-03-20.csv”, for easier archiving and management.
Three, Advanced Usage Tips
- Customize Scan Columns: Right-click on the table header of the result list and choose “Choose Columns…”. You can add or hide displayed information columns, such as “NetBIOS Name” and “Response Time”. Customizing the view can make the information more focused.
- Save and Load Scan Configurations: After setting the scan range and mode, you can save the configuration as a .cfg file through File → Save Configuration. You can quickly load it again through File → Load Configuration. This feature is especially useful for IT administrators who need to monitor multiple network segments on a regular basis.
- Parallel Scanning and Speed Optimization: In Preferences → Scanning, you can adjust the number of threads (threads). Increasing the number of threads (e.g., 50-100) can significantly improve the scanning speed, but you need to consider the network device load. According to experience, setting 64 threads is a good balance for a 1 Gbps network.
- Scheduled Scans: The software supports scheduled tasks. You can set up regular (e.g., daily, weekly) scans through Scan → Schedule Scan…. This feature is essential for environments that need 24/7 network reliability.
- Ping and Network Diagnostics Integration: Select a device and use the menu Tools → Ping or Tools → Traceroute to perform basic network connectivity diagnostics without leaving the software. This reduces the cost of switching between applications and helps you locate fault points faster.
Four, Common Issues and Solutions
Issue 1: No devices are found, or only the local device is found.
Solution:
- Confirm that the IP range you entered is correct and matches your local network segment (you can check your local IP through the “Network Preferences” in System Settings). This is the most common mistake for beginners; make sure to double-check.
- Check the firewall settings. Your macOS firewall or security software may block ICMP Ping requests. Try temporarily disabling the firewall or allowing IP Scanner Pro in the firewall settings. According to Apple’s official support documentation, you can add an exception in “System Settings -> Network -> Firewall -> Options”.
- Try using the “Quick Scan” mode. Some network devices may disable responses to deep scanning protocols, which is common for IoT devices or old routers.
Issue 2: Scanning is very slow.
Solution:
- In Preferences → Scanning, increase the number of threads. However, please note that having too many threads can overload the router.
- Reduce the scan range by scanning smaller IP segments (e.g., scan 0-127, then 128-254). This can improve scanning speed.
- If you do not need port information, choose the “Quick Scan” mode. This mode is slower because it needs to probe ports.
Issue 3: Hostnames or vendor information cannot be obtained.
Solution:
- Ensure that you are using the “Deep Scan” mode. The “Quick Scan” mode does not attempt to obtain these details.
- Some devices (like network cameras, switches) may not have or broadcast hostnames. These devices typically only respond to basic network protocols.
- Vendor information relies on the database of MAC address prefixes. If the device has a new or obscure MAC address, you may not be able to identify it. In this case, you can manually add MAC address records, and the software supports custom MAC vendor databases.
Issue 4: The software prompts “No Permission” or some scan features are disabled.
Solution:
- Some deep network scans require root permissions. Try exiting the software and starting it again with the terminal command
sudo (e.g., sudo open /Applications/IP Scanner Pro.app). After the first authorization, you will not need to repeat this process in the future.
- For the first run, grant the necessary network access permissions as prompted by macOS. If you previously denied access, you can re-enable it in “System Settings -> Privacy & Security -> Network”.
Issue 5: The CSV file exported from Excel displays乱码.
Solution:
- This is due to encoding issues. When exporting, try setting the encoding format to “UTF-8 with BOM”. Excel has the best compatibility with this encoding.
- Alternatively, you can import the CSV file into Excel through “Data → From Text/CSV” and manually select the UTF-8 encoding during the import process.
Assume your company’s department reports network sluggishness, and you suspect that some devices are hogging bandwidth. With IP Scanner Pro, you can do the following:
The entire process took less than five minutes, significantly improving efficiency over traditional methods. This is precisely what IP Scanner Pro offers—transforming network management from “reactive firefighting” to “proactive defense.”
