Those are Google Public DNS's. Is this what you have setup in your router setting? By default you should be using your ISP's DNS(s). Please check your router's DNS setting...
Others would choose to add a secondary Public DNS only if they are having issues to some websites, but the Primary DNS should be your ISP's.
