Selfishnet V3 May 2026

This report provides a detailed overview of SelfishNet V3, a network management tool designed to monitor, limit, and block internet bandwidth for devices connected to a local area network (LAN). What is SelfishNet V3?

SelfishNet V3 is a lightweight, portable network utility that leverages ARP spoofing (Address Resolution Protocol) to intercept and control traffic on a network. It allows a user to monitor all devices connected to their Wi-Fi or Ethernet and selectively manage their internet speed or access. It is often used for troubleshooting, managing bandwidth hogs in shared networks, or limiting access for specific devices. Core Features of SelfishNet V3

Device Discovery: Scans the network to identify all connected devices, displaying their IP and MAC addresses.

Bandwidth Control: Enables users to set download and upload limits for specific devices to prevent a single user from consuming the entire network bandwidth.

Blocking Functionality: Provides the ability to completely block internet access for specific devices (Mac spoofing). Selfishnet V3

Real-time Monitoring: Shows real-time network traffic statistics for connected devices.

Portable Application: It does not require a formal installation process, operating as a portable application. System Requirements and Installation

OS Compatibility: Compatible with various Windows versions, including Windows 7, 8, 10, and 11, usually requiring the "Win7 and up" folder version.

Required Dependency: WinPcap must be installed on the system for the software to capture network packets. This report provides a detailed overview of SelfishNet

Permissions: The application requires administrator privileges to function correctly.

Hardware Requirements: The Wi-Fi chipset must support "monitor mode" to intercept traffic properly. Important Considerations and Risks

ARP Spoofing Risks: SelfishNet works by sending fake ARP messages, which can cause network instability, leading to intermittent connectivity for other users.

Security Vulnerability: ARP spoofing can be exploited by malicious actors to perform man-in-the-middle attacks, potentially allowing them to intercept sensitive data. managing bandwidth hogs in shared networks

Ethical Use: It should only be used on networks you own or have explicit permission to manage, as its use can be disruptive. A breakdown of the installation steps for Windows 10/11?

1. Router QoS (Quality of Service)

Most modern routers (Asus, Netgear, TP-Link) have built-in QoS settings. Instead of throttling specific people, you prioritize specific traffic. For instance, you can set "Gaming" as high priority and "Streaming" as low priority. This affects all users fairly.
