Some university networks are run tightly, others are rather loose when it comes to security, monitoring and debugging network cables that are syncing up at lower speeds. Really depends on who is staffing the IT team...
Many older universities give you a public IPv4 address with no NAT when you plug into a network port.
OP, one neat thing you should try is broadcasting a /25 through /29 and seeing which ISPs this is routable from (eg: Lumen (aka Centurylink/Quantum), Verizon, T-Mobile, AT&T, Comcast, etc). There are a number of blocks smaller than /24's being broadcast, and it would be quite interesting to see which ISPs are willing to route traffic to smaller blocks.
