IP Messenger is a free, open-source, serverless local area network (LAN) communication tool used for instantaneous messaging and high-speed file sharing. Originally created by H. Shirouzu, it functions without requiring an internet connection or any centralized server administration. Because data travels entirely within your local network, transfer speeds are exceptionally fast and are only limited by your local router and network hardware capabilities. Core Features
Serverless Architecture: It operates via TCP/IP (UDP) protocols, completely bypassing cloud and external servers.
Automatic Peer Detection: The software automatically broadcasts across the LAN to detect other active users instantly.
Fast File and Folder Sharing: You can drag and drop entire folders or individual files to transfer them immediately.
End-to-End Security: Text communications are kept safe using RSA-2048bit and AES-256bit encryption algorithms.
Screen Capturing: It includes a built-in utility to capture customized screen regions and send them as inline message images.
Send Queue Manager: If a recipient goes offline or becomes inactive, the application places the message in a background queue to send automatically once they return. Strengths & Limitations IP Messenger – Download
