During an investigation to chase down the mysterious City Hunter, the prosecutors track down the IP address to the Blue House. Uh oh... our protagonist is in trouble. Or is he?? Here's the IP address: 192.168.1.123
Anyone who's configured a router or a home network would see this number and go "Oh wait, this looks vaguely familiar."
That's right. 192.168.1.xxx is IP address used for local area network. 192.168.1.1 is sometimes referred to as the home IP address (usually points to a router) and anything that follows in 192.168.1.xxx would be the computers connected to a local network. There's no way for you to track down anyone with this type of IP address.
Sorry prosecutor. But you just got pwnd.
