pystun3

Pystun3 is a command line tool for discovering the public IP address and port of a NATed server. It provides a simple and convenient way to determine the external IP address and port as seen by the internet. The tool is written in Python and is a successor to the original pystun tool. Pystun3 uses the STUN protocol to communicate with a STUN server and obtain the external IP address and port of the server. STUN (Session Traversal Utilities for NAT) is a standard protocol used for NAT traversal in VoIP and real-time communication applications. The tool supports both IPv4 and IPv6 protocols, making it compatible with different network configurations. Pystun3 is open source, allowing users to enhance and modify the tool according to their specific requirements. It is platform-independent and can be used on various operating systems, including Windows, MacOS, and Linux. The command line tool provides a user-friendly interface with options to select STUN server, display verbose output, and specify timeout settings. Pystun3 is a valuable utility for network administrators, developers, and system operators to troubleshoot network connectivity issues and ensure proper NAT traversal.
