SelfishNet disrupts this flow using a technique known as (or ARP Poisoning):
Allows you to set precise speed limits (in KB/s) on a device-by-device basis.
While modern routers offer Quality of Service (QoS) settings to manage bandwidth, these features can be notoriously complicated to configure. Enter , a lightweight, classic network management tool that gives users direct control over their local area network (LAN) bandwidth allocation.

Because ARP spoofing requires low-level control over network hardware, SelfishNet must always be executed by right-clicking the application and selecting Is SelfishNet Safe and Legal?
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.
Because SelfishNet v0.1 Beta is an older utility that relies on low-level packet interception, setting it up on modern operating systems like Windows 10 or Windows 11 requires a few specific prerequisites and compatibility adjustments. Prerequisites
The software also foreshadowed the debate around . If SelfishNet was user-controlled greed, then Comcast throttling BitTorrent was corporate-controlled greed. Both were controversial for similar reasons. Discover that natively supports Windows 11
The core features of SelfishNet v0.1 Beta are straightforward but powerful:
Once you have downloaded the program, simply extract the archive to a folder of your choice. SelfishNet is a portable application, meaning it does not require a traditional installation process.
