NetCut Defender is a free security tool from designed to protect your device from ARP (Address Resolution Protocol) spoofing attacks, including those initiated by other Key Features of NetCut Defender ARP Spoofing Protection : It is specifically built to guarantee 100% protection

Secondary Feature: "One-Tap Fast Internet Recovery"

• The Problem: Sometimes, even if the defender blocks an attack, the internet remains slow or disconnected because the network "handshake" was interrupted.
• The Solution: A large "Repair Connection" button on the home screen.
• What it does: With one tap, it forces the Wi-Fi radio to reset, clears the ARP cache, and requests a fresh IP address from the router. This fixes "Zombie" connections (where you are connected to Wi-Fi but have no internet) instantly without needing to reboot the phone.

: Once installed, the app runs in the background. It doesn't require complex configuration; you just turn it on and let it work. ARP Spoofing Shield : It works by detecting and blocking ARP spoofing

Better modern alternative:
Install ARP Guard from F-Droid → enable “Anti-ARP Spoofing” → it works like NetCut Defender but is updated and open-source.

Activation: Open the app and tap the Protect button. It will immediately scan and secure your active network adapter.
