The ISP provide devices that were connected and they ping to check if the ip was alive (This means that a internet connection was established).

1) Scan ISP subnet for all ips
2) Ping them to check who is alive

The problem with that scene, was they said "anyway of tracing"- with "tracing" being the operative word.

Establishing a connection Is one thing, tracing It's origin Is something else.
