So I'm playing with WebRTC and I've found that you can get public IP and local IP of other computer.
Here is my code that show IP https://codepen.io/jcubic/pen/yvMeRg?editors=1010 (the code is used to transfer the files between computers but it also show the IP of other party).
Can I with this information some how send a packet to the other party? Or the route the packet travel is something that is decided by routers and protocols.
Can anyone do something with this information to harm the person behind the NAT?
