Any chance this module can see a private IP behind TOR or a VPN - or a VPN and TOR?
STUN IP Address requests for WebRTC
https://github.com/diafygi/webrtc-ips
It seems like this would fit right in with this module to report IPs where others could not.
This might need a user-facing option to opt-out, while also providing an option for the site developer to allow opting out or not.
What this does
Firefox and Chrome have implemented WebRTC that allow requests to STUN servers be made that will return the local and public IP addresses for the user. These request results are available to javascript, so you can now obtain a users local and public IP addresses in javascript. This demo is an example implementation of that.
Additionally, these STUN requests are made outside of the normal XMLHttpRequest procedure, so they are not visible in the developer console or able to be blocked by plugins such as AdBlockPlus or Ghostery. This makes these types of requests available for online tracking if an advertiser sets up a STUN server with a wildcard domain.
Code:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body>
<h4>

</a>
</h4>
<p>
This demo secretly makes requests to STUN servers that can log your
request. These requests do not show up in developer consoles and
cannot be blocked by browser plugins (AdBlock, Ghostery, etc.).
