    don't have any devices that should connect between themselves and media routers are disabled in about:config, I am confused about this connections, on some devices I don't have such traffic with chrome.exe
    if I block this Internet is gone on chrome

    This address is a IP multicast.

    I hear this alot, but can it be dangerous, you too get multicast ip on chrome?
    As if everyone knows what is multicast but if a non techie tries to find how this can be exploited he finds nothing useful, only that it is a multicast (obviously)
    I don't get such on other browsers and not everytime on chrome , just this device
    I am thinking it might come from some addon/extension

    "224.* is a multicast "domain", wherein various apps will use it to connect to other apps etc." I do have browser addons

    so my question in short is, is it typical for chrome.exe? or I should investigate further

    I don't get it, it seams to be jumping around between extensions so removing one helps for a limited period of time only

    the option for disabling it was the first thing I did, didn';t help though, also its random, on some pcs it doesn't want 255.255 but the normal dns I have set

    according to some forum user there is possibility of Windows using Shell32 DLL and API for Bing functionality in Windows 8 and later versions since that IP seems to point to Bing search server.

    On some systems chrome doesn't connect to 255 (...) but normal chrome ip addresses

    ok found something here https://www.lifewire.com/how-to-turn-off-chromecast-4801906#:~:text=Open%20a%20new%20Google%20Chrome,select%20it%20from%20the%20list.
    but apparently it is not possible to disable chromecast
