Masses of Multicast stream started/ended/leave/join events in EE router log

ConfusedRaccoon · ‎18-11-2022

As title, my PC x.x.x.13 is spamming masses of Multicast events, joining, leaving every 10 seconds or so.

18:54:53, 18 Nov. Multicast event client leave group:224.168.100.1 client:192.168.1.13
18:54:53, 18 Nov. Multicast stream ended by client 192.168.1.13
18:54:43, 18 Nov. Multicast stream started by client 192.168.1.13

It's constant, and hits the Limit of MCST log after 15 minutes or so.

~~I have no idea what the 224.168.100.1 is~~ The unknown IP seems to be part of a multicast network, but I've no idea what or why it's happening. Is there any way I can track it down? Maybe something like Grammerly is trying to update its data base or something, I don't know.

Interesting, or not, developement. I started to reinvestigate this little enigma last night as I saw my IP sending these Multicast events nearly twice a second.

Looking like this:

I unpluged my ethernet cable and my wife's PC started pinging these events. Roughly every minute:

I've plugged my Ethernet cable back in and it's remained "quiet". While my Wifes PC still sends these out every minute or so. Still no idea what or why or even if it's something to worry about. I play a fair few online games and I wonder sometimes if this might be why sometimes I struggle with ping and latency? But I might be grasping at straws.

I Had the same problem and after a bit of investigation.

In my case, It was my network Printer Broadcasting its IP and looking for printjobs.

hope this helps
