: You can assign specific upload and download speeds (in KB/s) to any device on the network.
Although the original v0.1 beta was a basic utility, it packed several powerful features that have been refined and expanded upon in community-driven versions (up to v3).
The following is a draft white paper for , a legacy network management utility used for controlling bandwidth allocation on local area networks (LAN). Technical Overview: Selfishnet v0.1 Beta

As SelfishNet grew in notoriety, so did defenses. Network administrators fought back with three primary methods: selfishnet v0.1 beta
Understanding SelfishNet v0.1 Beta: The Ultimate Tool for Bandwidth Control
Click the icon to populate the list of devices.
: SelfishNet sends "bogus" ARP requests that falsely claim the host computer is the gateway. The Interception
In the "Download" or "Upload" columns, input the maximum rate (in K/s) you want to assign to that device 1.2.1. : You can assign specific upload and download
: The software detects all devices connected to the same Wi-Fi or Ethernet network and displays their IP and MAC addresses. Bandwidth Control
In the end, SelfishNet wasn't a tool. It was a lesson in digital ethics wrapped in a buggy executable.
Modern routers have built-in dashboards allowing you to prioritize traffic by device or application (e.g., giving gaming or video conferencing priority over background downloads) safely and permanently.
Because it uses ARP spoofing to function, some antivirus programs might falsely flag Selfishnet as malicious (like a Trojan or hacking tool). Technical Overview: Selfishnet v0
Because Selfishnet relies on ARP spoofing, it can easily disrupt workflows or be used maliciously on networks without your permission. Use these strategies to defend your network. 1. Enabling Dynamic ARP Inspection (DAI)
Once you have identified the device consuming too much data:
In the or Upload columns, double-click and type a numeric value in KB/s to restrict speed.
Right-click SelfishNet.exe (or Selfishnet-Win7.exe for newer Windows), choose Properties , go to the Compatibility tab, and check "Run this program as an administrator". Using the Interface

While it is a fascinating piece of software history, it is also a product of its time—unstable, unsupported, and a potential security risk if downloaded from untrustworthy sources. Its modern successor, SelfishNet V3, offers a safer and more stable way to explore these capabilities. Ultimately, SelfishNet serves as a powerful reminder that in our interconnected world, the tools of control are often just as accessible as the networks they seek to manage.
