Solved Constant weird IP traffic

Since the last recent update I have had constant IP upload/download traffic to MAC addresses that I cannot determine where they are (see attached). This is constant traffic all day and I wish I knew what was being transmitted.

Has anyone had this on their PC?

IPv6 addresses that start with FE80 or really just FE are link local addresses. That means they are not internet routable and can only communicate with devices local to the lan segment.
Port 5357 is used by WSD About Web Services on Devices - Win32 apps

This traffic is likely benign

Those are IPv6 addresses, not MAC addresses.

According to this, it could be legitimate, but it could also be malicious:

I have Network Discovery set to 'ON' for Private Networks and 'OFF' for Public Networks. My wife's Win 10 Pro PC is the only other PC on my network as I occasionally send files to her Public folder and she uses my printer for printing. For Public Networks, Discovery is set to 'OFF'.

I rummaged around the Ethernet settings and found that:

......:8d2f in the Local Address is my Ethernet connection.
.......fe70:62f is my HP Printer (see attached)

So I think my PC is communicating with my printer, although why and with such a constant communication stream I wouldn't know. At lease it's not going outside my network.

Thanks for putting me on the IPv6 track. Very much appreciated. I've also included a grab of my Network monitor showing the traffic.
