.SYNOPSIS
   Fetch the used interface for our Windows System
.DESCRIPTION
   Newer Windows systems provide a Cmdlet 'Get-NetRoute' for fetching the
   network route configurations. Older systems however do not provide this
   and to ensure some sort of backwards compatibility, we will have a look
   on our route configuration and return the first valid interface found
.FUNCTIONALITY
   This Cmdlet will return first valid IP for our interface
.EXAMPLE
