Selfishnet V0.1 Beta Jun 2026

When you launch SelfishNet, it scans your local network to discover all active IP addresses and their corresponding MAC addresses.

Displays the exact download and upload speeds (in KB/s) that each device is actively consuming.

SelfishNet v0.1 beta was never meant to be an enterprise tool. It was a proof-of-concept wrapped in a simple UI.

The software works by utilizing a technique known as (Address Resolution Protocol spoofing). By sending forged ARP messages across the local area network (LAN), SelfishNet positions your computer as the intermediary "gatekeeper" between the router and all other connected devices. This allows you to intercept, throttle, or terminate their data packets at will. Core Features of SelfishNet

is a conceptual framework designed to optimize decentralized network resources by prioritizing individual node utility—a "selfish" approach that paradoxically improves overall system resilience. Abstract

: Nodes automatically drop traffic that doesn't provide a signed "Reciprocity Token."

, tricking other devices into thinking your computer is the network gateway. Installation Requirements To run SelfishNet v0.1 beta (often found as SelfishNet_v0.2_beta_vista.exe for newer Windows versions), you must have the following:

I should delete my patch. I won't. That's the problem with beta software. Once you see how the world really works, you can't uninstall it. When you launch SelfishNet, it scans your local

: Upon launching, you will be prompted to choose the network interface (Wi-Fi or Ethernet) you want to monitor.

I didn’t mean to break the network. I just wanted a little more bandwidth for myself.

This is where legacy network administration tools like come into play. SelfishNet is a portable Windows-based utility designed to grant users complete command over their local network traffic. It allows you to discover connected devices, throttle their download and upload speeds, or block their internet access entirely.

By week two, the mesh had fractured into islands of mutual suspicion. No node trusted another unless it saw proof of selfish behavior first. My own logs showed my node talking to only four others — all running versions of Selfishnet they'd compiled themselves. It was a proof-of-concept wrapped in a simple UI

: This driver is essential for the software to capture and inject network packets. Administrative Privileges : You must right-click the application and select "Run as administrator" to allow it to access network data. .NET Framework 3.5

SelfishNet v0.1 Beta is a network administration tool for Windows operating systems that allows users to monitor, limit, or entirely block the internet speed of other devices connected to the same Wi-Fi or Ethernet network.

In the early days of shared broadband internet, a common household or office problem emerged: one user downloading large files or streaming high-definition video could instantly paralyze the network for everyone else. While modern routers feature advanced Quality of Service (QoS) settings to manage traffic, older networks lacked elegant solutions. Enter , a legendary, lightweight network management utility that gave individual users absolute control over their Local Area Network (LAN).
