Selfishnet V0.1 Beta

Select your active network adapter from the drop-down menu and click .

SelfishNet v0.1 Beta is a popular, legacy network administration utility for Windows operating systems. It allows a user to monitor all devices connected to their local WiFi or ethernet network and manually limit or completely block their internet speeds.

Before SelfishNet, ARP poisoning was an abstract concept in networking textbooks. This tool let a curious high school student see the effect in real-time. You could kick your own laptop off Wi-Fi, then watch the packet capture in Wireshark. It was a spectacular learning aid.

Why should anyone care about an unstable beta from fifteen years ago?

SelfishNet v0.1 Beta — lightweight Windows network monitoring and bandwidth control utility (early beta). Designed to display active hosts on a LAN and allow per-host bandwidth limiting and blocking by manipulating ARP and network adapter settings via a GUI.

SelfishNet v0.1 Beta provides a minimal, reproducible testbed for selfish behavior in wireless mesh networks. Despite beta limitations, it confirms that even moderate selfishness severely degrades PDR. The framework is open-sourced at [your GitHub link].

SelfishNet v0.1 Beta is a network administration tool designed for Windows that acts as an . It allows a user to monitor all devices connected to the same local area network (LAN) or Wi-Fi, view their IP and MAC addresses, and, most importantly, limit their download and upload speeds or block their internet access entirely . Select your active network adapter from the drop-down

: When a device needs to reach the internet, it asks the network for the MAC address of the gateway (the router).

The first step to control is awareness. SelfishNet uses ARP requests to scan your local network. Within seconds, it populates a list of all active devices. It displays critical information, including the device's IP address, its unique MAC address, and the manufacturer's name (e.g., Apple, Samsung, TP-Link). This allows you to identify exactly which device belongs to which user.

When SelfishNet is activated, it sends a broadcast telling every other computer on the network, "I am your gateway to the internet. All your traffic should come to me first." Simultaneously, it tells the router, "I am every computer on this network. All traffic for them should come to me first." This positions your machine as a "man-in-the-middle." All internet traffic flows through you, granting you complete oversight and control over each byte passing through the network.

Although it is an older tool, the v0.1 beta remains popular for its simplicity in managing, limiting, or even blocking devices on a Windows network. What is SelfishNet v0.1 Beta? You will see columns labeled , IP ,

Displays the real-time download and upload speeds of every single device on the network.

Understanding how this classic tool operates offers valuable insights into network vulnerabilities, the mechanics of Address Resolution Protocol (ARP) spoofing, and the best ways to protect your own devices. What is SelfishNet v0.1 Beta?

Click the "Block" (x) icon to immediately cut off a device's internet.

: Other devices begin sending their data packets to the host computer instead of the router. This places the host "in the middle," giving it the power to throttle or drop those packets before they reach the actual internet. Setup and Requirements
