I was checking my network activity from Resource Monitor and noticed chrome sending data to 239.255.255.250. Looked it up and it seems to be an address associated with Plug & Play devices. What I would like to know find out, is if this is normal. I can't remember if it did it before, but do I need this? What is it actually trying to do? I made a post in networking and was linked info about svchost making the connections, but not chrome. Any help is appreciated :)

Here is some info that should get you started; In addition, I suggest that you hop over to the malware section and have one of the staff check you out. It won't hurt.

You can also try disabling this in your host file, it's worth a try. You can always roll it back if it causes problems.

Comment: Addresses starting with a number between 224 and 239 are used for IP multicast. IP multicast is a technology for efficiently sending the same content to multiple destinations. It is commonly used for distributing financial information and video streams, among other things.

re: the above link: remember this is old and applies to Windows XP, so if this same applies to W7 and later is questionable.

Thanks for the info. I don't think its malware, had then check me out a month ago an got the all clear, and the amount of data is too small. Question I would ask is do you see something similar?

No, not on my machine or any of the others. I use Firefox, so maybe it's a Chrome thing?

That would seem to be similar to what the links I posted refer to; unfortunately, I do not use Chrome. Maybe someone with more experience with Chrome can help you there.

From doing a quick Google search, Chromecast would seem to be the culprit.

It is possible. Have you used a Chromecast in the past?
