Always take traceroute return codes with a pinch of salt. It's entirely
possible to configure a router such that it replies with 192.168.x.x
addresses if you traceroute through it, depending on the implementation
of the OS it's running.

Basically routers respond with their management interface (if they're
simple, or the config tells them to, or you're on a different network)
address - what you see inbound may be different to outbound. Be careful!
