ZoneAlarm shows "NetBIOS Name" requests from the following IPs , , , and more, all UDP.
It happens everytime I connect to my ISP, dial-up, dynamic IP.
As far as I know those are reserved for private networks. So they are from my ISP network machines or users. Is that right?
Is there any way to know which machine is trying to get my "NetBIOS Name" and why it is doing it, while it dosen't happen in other ISPs (others that I have used at least)?
