Nah, NAT doesn't provide the security; firewalling does.

Besides, what kind of controlled unclassified information could possibly be residing on dormitory networks?

Indeed! The only reason they're doing this is clearly that they want to sell even more IPv4 addresses. Because even with the current /9, it's more than enough to go around the campus.

Indeed! If anyone needs to feel the squeeze for IPv4 to make a move to IPv6, it is AWS... which MIT is conveniently selling the IPv4 addresses to!

Moving IPv4 to NAT and moving to IPv6 seems orthogonal.

Good question indeed. Why didn't MIT give more time to move, and in fact gave absolutely no notice, such that WMBR, the campus radio station, had to scramble to get their online radio back online again?
