You're a complete retard, and that isn't how networking works at ALL.
At most you would change the MAC that the router is seeing if it's directly talking to your card and it would change the internal IP. AKA: you can do the same thing by restarting your router.
Long story short, you should probably get yourself checked - you most likely have downsyndrome.
PS: If it's even possible for them to have your devices MAC, you can easily change it, or spoof it.
