Selfishnet V3.0.0 Windows May 2026

is a legacy network management utility for Windows designed to give users granular control over their local area network (LAN). It is primarily known for its ability to identify all connected devices and selectively limit or block their bandwidth consumption. Core Functionality

In shared living environments—such as university dormitories, shared apartments, or open-plan offices—a single user engaging in high-bandwidth activities (like 4K streaming, large game downloads, or video conferencing) can cripple the latency for everyone else. Standard router configurations are often inaccessible to tenants or require administrator passwords. Selfishnet v3.0.0 democratizes network control by exploiting how standard, unsecured networks handle Address Resolution Protocol (ARP). By sending ARP replies to the gateway, Selfishnet convinces the router that the user’s computer is the legitimate path for all traffic.
