RtWLan.exe IGMP pop up


I received a pop up on my firewall for RtWLan.exe requesting access to an IGMP protocol with the IP adress

I allowed the access since I consider my RtWLan as a safe application, but I dont recognise the IP adress. Is this IP safe?

Kind regards,


If I remember correctly is the multicast adress in ipv4, so perhaps you are sending IGMP packets so several hosts on the network? Though I am not completely sure so you might want to wait for someone more experienced with networks to reply.

It’s probably Simple Service Discovery Protocol (SSDP)… Windows Service… UPnP related and it’s usually nothing to worry about.

PS If the port number was 1900 UDP, then SSDP it is.

Thanks a lot for the replies. Its good to hear that most likely its nothing to worry about. I’ll just keep it running like that then. Thank you for taking the time to reply, its greatly appreciated.
