In the main interface, click the blue globe icon (Network Discovery). You may need to click it a few times as Selfishnet scans the network and populates the list of connected devices.
Operates entirely from a single endpoint machine, removing the need for router passwords or firmware modifications. How SelfishNet Works: The Technical Mechanics
Continually spamming a network with fake ARP packets causes noticeable traffic overhead. On busy networks, this can slow down performance across all connected hardware, including the host computer.
(Optional) Set the compatibility mode dropdown to or Windows Vista if the application fails to initialize on Windows 11. Click Apply and hit OK . Step 3: Running the Application
Mac Spoofing. See how many devices are connected to your network. Check the IP's and Mac addresses of the devices on your network. selfishnet v0.1 beta
You will see columns labeled , IP , MAC , Download , Upload , and Block .
This is a classic compatibility issue with modern Windows frameworks. Ensure that you have enabled compatibility mode for Windows 7 or Windows XP in the file properties. The Network Discovery List is Empty
Using ARP spoofing or intercepting network traffic can disrupt other users and may be illegal on networks you don’t own or administrate. Only run this on your own home or lab network with permission.
SelfishNet v0.1 Beta is a Windows network monitoring and bandwidth-control tool that inspects devices on a local LAN and lets you view usage, block devices, or throttle bandwidth per device using ARP spoofing and Windows packet APIs. In the main interface, click the blue globe
You do not need the router's admin username or password to use this tool, making it ideal for student dorms, shared apartments, or public networks. Step-by-Step Guide to Installing and Using SelfishNet
While effective, using tools like SelfishNet v0.1 Beta comes with responsibilities and potential downsides.
When you activate SelfishNet, the software sends forged ARP messages across the local network. It tricks the other connected devices into thinking your computer is the network router, and simultaneously tricks the router into thinking your computer is the target device.

A toggle switch to completely sever a device’s internet connection. Limitations Volatility:
To limit a device, click into its or Upload (Cap) column and enter a maximum threshold numerical value in kilobytes per second (e.g., entering 50 restricts that device to roughly 50 KB/s).
SelfishNet achieves its network dominance without touching the physical router by exploiting a core, trust-based networking protocol known as . The Concept of ARP Spoofing
