[::]:123 Could be related to your router configuration, you could worry, if there's a complete IP like the one you've got has an ongoing connection with your PC, or an unknown web server that a keylogger could be hosted on.
I do not use a router. I have a cable modem like this one http://www.digitallanding.com/wp-content/uploads/2012/06/Comcast-Cable-Modem1.jpg given to me by my cable TV / Internet provider.
Thanks
That lets you access the router/modem control-page, where you could configure , reset, or restart your router/modem
They're yours and nobody could access them unless they have your modem/router
So it's completely normal.
