Selfishnet: V0.1 Beta

Incorrect use—such as blocking the router itself—can temporarily disrupt internet connectivity for everyone until the app is closed.

SelfishNet v0.1 Beta is a network management software application designed for Windows utilities. It allows an administrator—or any user running the software—to monitor, restrict, or completely block the internet bandwidth of other devices connected to the same Local Area Network (LAN).

If you want, I can:

Modern Windows security protocols often restrict legacy network injectors. Extract the SelfishNet folder to your desktop.

You will see a list of IP addresses. Use the "Download Rate" and "Upload Rate" columns to set limits, or the "Block" checkmark to stop access. selfishnet v0.1 beta

Many modern Antivirus programs may flag SelfishNet as a "Trojan" or "PUP" (Potentially Unwanted Program) because it uses ARP spoofing techniques. If you trust the source of your download, you may need to whitelist the application.

Tricked by these fake messages, every target machine updates its internal routing table. Instead of sending web requests straight to the physical router, they route all upload and download traffic directly through the computer running SelfishNet.

remains a legendary tool in the world of networking utilities. It’s perfect for the "power user" who needs a quick, effective way to ensure their gaming session isn't ruined by a background Windows update on another laptop. While modern routers now have built-in "Quality of Service" (QoS) settings that do similar things, SelfishNet offers a level of manual, real-time control that is hard to beat.

Managing a shared internet connection can be incredibly frustrating when a single user consumes all the available bandwidth. Whether it is a roommate downloading large files, a family member streaming 4K videos, or background updates choking your ping during an online game, network congestion disrupts productivity and entertainment.

Click the "Network Discovery" button (usually a hand icon) to scan for connected devices.

The software falsely tells all other devices: "I am the default router/gateway."

Segmenting a network into VLANs limits the scope of an ARP spoofing attack. If an attacker compromises a device in one VLAN, they cannot ARP spoof devices in a different VLAN because they are on separate broadcast domains.

The core features of SelfishNet v0.1 Beta are straightforward but powerful: Use the "Download Rate" and "Upload Rate" columns

: Nodes dynamically restrict outgoing bandwidth during peak local usage, ensuring the host machine never loses performance.

A prompt will ask you to choose your . Select your active Ethernet or Wi-Fi card from the drop-down menu and click OK.

I can, however, explain the networking concepts that Selfishnet exploits, such as Address Resolution Protocol (ARP) spoofing, and discuss how network administrators detect and mitigate these types of attacks.

Using Selfishnet is straightforward, but there are a few critical steps to ensure it works correctly:
