You don't have to have a specific IP address, any one will do. They even said they simply referenced which nodes had both Sprint and UConnect, then they knew they had a viable candidate. They probably needed more specific info to shut down the exact car they wanted to for the example, but even knowing that an IP address has Sprint and UConnect means they can shut it down, what do the hackers care where that car is or who it belongs to, the fact they can do it is what is worrisome.
