pystun3: Make a STUN request.
$ pystun3
try on your machine

The command "pystun3" is a command-line tool used for network troubleshooting in Python. It is designed to determine the public IP address and port mapping of a NAT (Network Address Translation) gateway or firewall.

When you run the "pystun3" command, it initiates a STUN (Session Traversal Utilities for NAT) protocol connection to a STUN server. STUN servers are typically available on the internet and help to identify the presence and properties of NAT devices in a network.

The pystun3 command performs the following steps:

  1. Sends a STUN request to a STUN server.
  2. Receives the response containing the public IP address and port information.
  3. Prints the gathered information on the command line for the user to see.

This information is useful for diagnosing network connectivity issues or understanding how network traffic is being handled by NAT devices.
