Caller: Scammer - National Broadband Network

Scammer pretending to be from the National Broadband Network says my broadband IP address is being used in two separate countries at the same time, and asked me to tell him what colour light is showing on the router.
I explained that that was a bit difficult as I don't have a router or broadband connection. He was very surprised and asked what system I used. I said that it was none of his business, thanked him for his call and hung up the call.
