Nope. That is a probe from Java running on your computer to your local network, so the ISP doesn't matter.
But we are (in the next couple of days) going to add code to check for these UPnP vulnerabilities: The actual vulnerability space is higher, HD. Moore only found EXTERNAL facing UPnP, internal is also a problem and can also be vulnerable.
