Not necessarily. It might deform enough to diffuse the the force of impact away from the impact. Like rubber.

Dude: Thank you for clearly stating my exact thoughts...

The IP address of record is associated to the MAC address of the cable/dsl router/modem/gateway. This does not imply anything about which device on the client side (private)of the network actually was conected at the time of the alleged transfer. If there was a wireless router it could be anyone. Or may a friend connected a laptop for a little while... Finally, maybe the IP address was highjacked on the public side of the network. Anyway... good luck.
