Are only routers showing up there? Are there programmes too? I can only imagine they may be your network but that's only a guess.
I don't have any in mine so maybe you should contact Technical Support for advice on that, it's free and available through Useful Links at the top of this page.
yes there are programms.
This happend under the mcafee service host.
it comes when i go my pc out of sleeping mode.
if i look some seconds later in the traffic control all those entry´s are gone.
It all happend after the update to sc 12.1
Must be some strange quirk of the machine waking up. I always have avoided Sleep or Hibernation modes because over the years I've found things don't always work the same afterwards and a reboot is then required.
