When I start capture on WireShark, my display is instantly filled with hundreds of SSDP packets being sent from my local IP address to the same IP, 239.255.255.250. Even when I have nothing else open on my computer other than WireShark. Is this normal? I've Googled it and there are lots of other people saying similar things but they always have slight differences and then the differences tend to be the focus of the subsequent discussion.
Is this normal activity? What's it doing? Why's it doing it?
Almost every packet has the info, NOTIFY * HTTP/1.1, except a few that are M-SEARCH * HTTP/1.1
Why does my computer feel the need to repeatedly notify this other server?
On further inspection it says the source is Shenzhen in China?? And does "20:32:33:c9:42:56" mean anything?
