I have what may be a simple issue, but it is something I've never noticed before, and I wanted to see if it was cause for concern or action was needed.
When checking something else with netstat.exe on a Windows system, I noticed the System Process listening on various ports - (137, 138, 139) from a local IP that is not my local IP.
Specifically, my local IP is 192.168.1.67 and the address shown is 192.168.56.1. I've never seen any local IP's on my network have an address that didn't have a '1' for the 3rd digit group, but more importantly, the System process is listing from somewhere on my pc but apparently not from my pc.
I'm essentially a novice when it comes to Network Protocols and such, so keep that in mind when answering.
