title: Discovering public IP programmatically
body: <p>I'm behind a router, I need a simple command to discover my public ip (instead of googling what's my ip and clicking one the results)</p>
  
  <p>Are there any standard protocols for this? I've heard about STUN but I don't know how can I use it?</p>
  
  <p>P.S. I'm planning on writing a short python script to do it</p>
