NetCut

NetCut NetCut for Android is a LAN network management app that scans IP/MAC devices, detects hidden users and ARP spoof attackers, and blocks or restores selected connections for better control.

NetCut

NetCut is a LAN network management and control utility built on the ARP protocol. By leveraging how ARP works, it can update the ARP cache entries on selected devices—using crafted ARP response packets—so it can temporarily block or restore network access for specific targets. It does this without needing to install any software on the devices being controlled.

With NetCut, you can quickly scan your local network to find IP and MAC addresses, disconnect or reconnect devices one-by-one or in batches, view network traffic, restrict WiFi access for specific devices, create scheduled control plans, and keep records of devices currently connected to your LAN.

Key Capabilities

• Quickly find users on WiFi: NetCut can detect connected devices on the same WiFi network even if your phone doesn’t have a valid IP address or isn’t currently allowed to use the WiFi’s internet. As long as your phone is connected to the WiFi, NetCut can operate.
• Turn users on or off: You can enable or disable network access for many types of devices, including phones and gaming consoles (e.g., iPhone/Android, Xbox, softphones, PS3/PS4, and others).
• Cut communication within the LAN: You can break network communication between two devices inside the LAN by assigning one device as a gateway, disconnecting the other user(s), and preventing them from communicating with each other. For example, disconnecting your phone from a set-top box (Apple TV, Google TV, Xiaomi box, etc.) can disable features like screen casting.
• NetCut Defender: Built-in defense that you can toggle on or off instantly with a single click.
• Re-scan when devices seem missing: Use scanning when you suspect there are still devices connected to your network but you can’t see them yet.
• Identify connected phone models: NetCut can list the types of phones detected on your network.
• Name devices for easier tracking: Press and hold any detected device, then enter a custom name in the pop-up window. This helps you remember and manage devices more easily.
• Detect ARP spoofing attempts: If someone tries ARP spoofing against your network, NetCut can show it directly so you can respond promptly.

Tips

Scan for Hidden or Unknown Users

If you believe additional devices are connected but not showing up, run a NetCut scan. This can help you spot unauthorized devices or devices that are otherwise hard to notice.

Personalize Device Names

Long-press any device in the list. A pop-up will let you assign a recognizable name, making it faster to identify specific devices later.

Check Phone Types

NetCut can display the phone types it detects on your network, which can be useful when troubleshooting or managing connected devices.

Watch for ARP Spoofing Attacks

NetCut can alert you if someone is attempting ARP spoofing on your network, helping you stay aware and take protective actions.
