If the space in question is post-1997 then yes, either renting space as an "end user" or failing to swip reassigned space as an ISP violates their agreement with ARIN. It could be reported as fraud making everybody unhappy. If the edu's space is a legacy assignment then they have no agreement with ARIN to violate. On a more practical level, you'll encounter three kinds of trouble: 1. Despite your best efforts, the school will receive some packets intended for you. Make sure you have a tunnel in place to catch them. 2. Reverse path filtering may trip you up if the school hasn't already addressed that with their ISPs. 3. Their own internal firewalls and access control mechanisms which have, over the years, been programmed to act on their entire address space.
