When I was at RIT, computers on both the residential and academic networks
received routable IPv4 addresses, since they've got a whole /16
(https://ipinfo.io/AS4385).

It was glorious. Residential (dorm room) IPs could serve every port except 25,
and students would frequently run web, IRC, and game servers out of their dorm
rooms. Academic could serve *every* port, and I did indeed run a mail server
from a Plan 9 box sitting on a desk in the CS department for several years.
