: Because many hosted downloads for network utilities contain modified code or malware, verify your download hashes using online sandbox analyzers like VirusTotal.
is a network management utility that was historically used for ARP spoofing — a technique that can intercept, monitor, or restrict other devices' internet access on a local network. While it has legitimate uses (e.g., network administrators testing security or parents managing kids’ screen time), it is more commonly associated with unethical or illegal activities like:
If the application opens but fails to list any devices except your own computer and the gateway:
Before opening SelfishNet, download and install or WinPcap . During the Npcap installation process, ensure you check the box that says "Install Npcap with WinPcap-compatible API mode" . If you skip this, SelfishNet will throw an error stating it cannot find the necessary driver files. Step 2: Download and Extract SelfishNet
Some antivirus programs may flag SelfishNet as a "Potential Unwanted Program" (PUP) or malware due to its network redirection capabilities. Conclusion selfishnet v3.0.0 windows
Before installing, remember to download only from the official GitHub repository, install WinPcap, and always run the program as administrator. With proper setup, SelfishNet can transform your frustration with slow internet into fast, fair, manageable network usage—all at the click of a button.
: Once the redirection is successful, all internet-bound traffic from targeted devices passes through the host PC before reaching the actual router.
Continuous ARP spoofing generates extra traffic on your local machine and can occasionally cause network instability or disconnect legitimate smart-home devices. Use it primarily as a temporary diagnostic tool rather than a permanent network architecture solution.
SelfishNet is primarily used in environments with shared Wi-Fi where one user may be hogging bandwidth through heavy downloads or streaming. : Because many hosted downloads for network utilities
: Because it interacts directly with network protocols, you must right-click the executable and select "Run as Administrator" .

If you want to entirely restrict a device from accessing the web, look at the final column labeled Block and check the corresponding box for that device. During the Npcap installation process, ensure you check
