One, Core Interface and Workspaces
After launching the software, the main interface is divided into several functional areas:
- 1. Toolbar: Located at the top of the window, it contains the most commonly used operation buttons, such as “Start Scan”, “Stop Scan”, “Add Scan Range”, “Whitelist Management”, and “Preferences Settings”.
- 2. Main View of Devices List: Occupies the central area of the window, displaying all scanned network devices in a table format. By default, the columns include:
- Icon Status: Clearly indicates the device’s online, offline, or newly discovered status.
- Custom Icon/Name: Users can set easily recognizable icons and aliases for devices.
- IP Address: The network IP address of the device.
- MAC Address: The physical address of the device.
- Device Name: The hostname obtained through NetBIOS or Bonjour.
- Manufacturer: The device manufacturer identified by the first few bytes of the MAC address.
- Last Online Time: The last time the device was detected.
- 3. Sidebar/Filter: Usually located on the left, used to switch to different scan views or filter devices, such as “All Devices”, “Online Devices”, “Whitelisted Devices”, and historical views under “Cumulative Mode”.
- 4. Information Panel/Preview Pane: When a device is selected, a detailed information panel may appear at the bottom or on the side, providing quick access to right-click menu options like Ping, port scanning, and remote wake-up (WOL).
Two, Complete Operation Flow: From Launch to Export
1. Create/Start Initial Scan
Operation: After launching the software, it usually automatically detects your local subnet (e.g., 192.168.1.0/24) and starts scanning.
Manual Control:
- Click the “Start Scan” button (a circular play button) or use the shortcut
Command + R to start the scan.
- Click the “Stop Scan” button (a square stop button) or use the shortcut
Command + . to stop the current scan.
2. Add Custom Scan Range
If the software did not automatically detect your subnet, or you need to scan a specific IP range:
- Click the “+” button on the toolbar or use the menu “Scan” -> “Add Range…”.
- In the pop-up dialog, input the starting and ending IP addresses (e.g., 192.168.1.1 to 192.168.1.254).
- Click “Add”, and the range will be saved and started scanning immediately.
Shortcut: New ranges can be added using the shortcut Command + N.
3. View and Customize Device Information
Custom Column View:
- Right-click the table header to select or deselect columns to display (e.g., hide the MAC address column).
- Drag the table header to reorder the columns.
Custom Device Icon and Name:
- Double-click the device name cell or right-click the device and select “Rename…”.
- Enter an easily memorable alias (e.g., “Living Room TV”, “Master Bedroom Printer”).
- Right-click the device icon cell and select “Change Icon…” to choose an icon representing the device type from the built-in icon library.
4. Use Cumulative Mode to Monitor Network Changes
This mode is used to record the historical state of network devices, helping to identify devices that occasionally connect or have gone offline.
- In the sidebar or menu “View”, switch to “Cumulative Mode”.
- The software will continue scanning and recording all devices that have appeared.
- In cumulative mode, you can select “Show Offline Devices” in the view options (usually found at the bottom of the interface or in the “View” menu) to display devices that were once online but are now offline in gray.
5. Use Whitelist to Filter Unknown Devices
Add trusted devices to the whitelist to quickly focus on new or unknown devices.
- Select a known, trusted device in the device list (e.g., your own computer or phone).
- Right-click the device and choose “Add to Whitelist…”.
- Confirm the addition and the device will be added to the whitelist.
右键点击，选择 “Add to Whitelist”，或点击工具栏的“Whitelist”按钮。
切换到 “Non-Whitelisted Devices” 视图，这里只显示未加入白名单的设备，便于排查潜在的网络入侵者。
管理白名单：通过菜单栏 “Scan” -> “Manage Whitelist…” 查看或移除列表中的设备。
6. Execute Advanced Operations on Devices
右键点击任一设备，会弹出上下文菜单，提供多种工具：
- Ping： 测试与该设备的网络连通性。会弹出一个新窗口显示ping的结果。
- Port Scan： 扫描该设备开放的TCP/UDP端口。在弹出的对话框中设置端口范围（如1-1024）后开始扫描。
- Remote Wakeup (WOL)： 向已关机的设备发送魔术包，使其启动。需要设备支持WOL且MAC地址正确。
- Copy Information： 可以快速复制该设备的IP地址、MAC地址等信息。
7. Export Scan Results
将当前设备列表信息保存为文件。
- 确保设备列表视图是您想要导出的状态（例如，是所有设备还是筛选后的视图）。
- 点击菜单栏 “File” -> “Export…” 或使用快捷键
Command + E。
- 选择保存格式（通常支持CSV、TXT等），命名文件并选择存储位置。
- 点击 “Save”。导出的文件将包含当前视图下所有可见列的数据。
Three, Advanced Function Usage Tips
- Quick Sort： 直接点击设备列表的任何表头（如“IP Address”、“Last Online Time”），即可按该列升序/降序排列，快速找到最新上线的设备或按IP顺序查看。
- Use Notifications： 在 “Preferences” -> “Notifications” 中，可以启用Growl或系统通知。当发现新设备或设备状态改变时，会弹出提醒，非常适合安全监控。
- Adjust Scan Speed and Threads： 在偏好设置中，高级用户可以调整扫描的并发线程数和超时时间。更快的扫描可能增加网络负载，更慢的扫描则更准确但耗时。
- Save and Load Configurations： 您自定义的列视图、扫描范围和白名单都会自动保存。如果需要迁移，可以在“File”菜单中找到相关导入/导出配置的选项。
Four, Common Issues and Solutions
1. Unable to Scan Any Devices
- Check Network Connection： Ensure the Mac is connected to the target LAN (Wi-Fi or wired).
- Verify IP Range： Check if the software’s automatically detected IP range is correct. You can view your Mac’s local IP address in “System Preferences” -> “Network”, and the subnet is usually similar (e.g., 192.168.1.x). Manually add the correct range.
- Disable Firewall： Temporarily disable the Mac’s system firewall or the firewall on the target device to test. Certain firewall rules may block ICMP or ARP probe packets.
2. Device Names Show as “Unknown” or IP Addresses
- Renaming： This is a normal phenomenon as not all devices broadcast their hostnames. You can manually rename them for identification.
- Port Scan： Sometimes, open service ports can provide more identifying information.
3. Device Status Doesn’t Update in Cumulative Mode
- Ensure Scanning is Not Stopped： Cumulative mode requires continuous scanning to update status.
- View Options： Confirm that the “Show Offline Devices” option is checked. Offline devices are displayed with different colors or icons.
4. Wake-on-LAN (WOL) Function Isn’t Working
- Support Check： The network card and BIOS/UEFI of the target device must support WOL and it must be enabled in the settings.
- Network Environment： WOL magic packets typically need to be sent within the same subnet. If across subnets, router support and static ARP binding or port forwarding may be required.
- MAC Address： Ensure the MAC address read by IP Scanner Pro is correct.
5. Software Becomes Laggy or Crashes
- Update to the Latest Version： Developers usually fix known bugs in the latest version.
- Check CPU and Memory Usage： Ensure there are no other programs running in the background that consume excessive resources.
- Reinstall the Software： If the issue persists, try uninstalling and reinstalling the software.
6. Scan Results Are Inaccurate
- Adjust Scan Threads： Reduce the number of concurrent threads to improve accuracy.
- Ensure No Interference： Ensure there are no other devices interfering, such as using the same IP addresses.
- Enable Slower but More Accurate Scan Mode： In the preferences, enable the slower but more accurate scan mode.
7. How to Batch Manage Devices
- Use the shortcut
Command + A to select all devices, then right-click to choose batch operations.
- Utilize the whitelist feature to quickly filter out device groups that need management.
- Export CSV files and use Excel for more complex data processing.
8. Software Occupies Network Bandwidth
- Reduce the number of scan threads in the preferences to decrease concurrent requests.
- Adjust the scan interval to a longer time.
- Perform large-scale scans during non-working hours.

六、 Practical Case: Home Network Device Troubleshooting
Assume you suspect unauthorized devices are connected to your WiFi. You can do the following:
First, open IP Scanner Pro, which will automatically scan the entire local network. Add all known devices (such as your iPhone, MacBook, smart TV) to the whitelist.
Next, switch to the “Non-Whitelisted Devices” view. If unfamiliar devices appear, such as one showing as “Unknown,” right-click on it and choose “Port Scan.”
If you find open certain common service ports, like port 80 (HTTP) or port 443 (HTTPS), try accessing its IP address directly in a browser. If a router or camera management page pops up, it’s likely an unauthorized device.
Finally, record the MAC address of this device, enter the router’s management interface, and add it to the blacklist or apply MAC address filtering. Repeat this process monthly to ensure your network environment is clearer and safer.
