IP address conflicts / locating

At our school, all our IPs are public and statically assigned. Because we're a large school, and IP management is decentralized, we often have IP address conflicts. Our resolution procedure is to call the network group which filters that IP address. Then we wait until the perpetrator calls the network group to say that the network isn't working. Then the perpetrator is told to use a different address, and the original computer can have that IP address back. This can work when people are merely making mistakes, however we're noticing rogue servers being installed, and when they get filtered, they simply move on to another address. I've asked if we can get a tool which will take as input the IP address, and give the switch port where this IP is active, identify where this switch is, and further identify to which building and room that port connects. Do other schools have this ability, or am I asking for too much?
