Why am I getting probed??

Since about 9pm on 7/10, I have been getting probes on port 6347 approximately once per minute!! My ZoneAlarm log confirms this.

To the best of my knowledge, I do not belong to Gnuetella, LimeWire, or any other network of this type. Since my ISP is Verizon, I do not have a static IP address, but I noticed today that if I log off and back on, it keeps the same IP address.

Since I have not used LimeWire (to my knowledge..!!), I am not sure how the service works, ie would the 'server' keep poking at my address if I never requested anything? Would it keep poking if some other user of Verizon had this address and signed up for LimeWire without knowing he did not have a static address..??

I have tracked the IP of the source probing me back to his ISP and have sent them a message about this probing just in case it is some idiot trying to bust in.

If it is a LimeWire (or other Gnuetella) source, and my IP has somehow gone static on me, how can I get it stipped?

P.S. Don't get me wrong...this Gnuetella network thing sounds like a valuable net application...I just haven't signed up yet 8-)

Thanks for any and all help.
