MIT enrolls more graduate students (approximately 6,000 in total) than  
undergraduates (approximately 4,000).

Let's assume 2 staff/faculty per student (don't we wish :).  So that  
would be 30K total.  Let's further assume 100 IP addresses per student  
to deal with laptops, server, other computers, routers, etc.  We're  
now at 330K.

That's no where near 25% of the /8 they have.  Good thing they are  
announcing a /15, /16, and a /24* originated from their ASN too.

Just so we are clear, I have no idea how many servers, computers, or  
other things MIT might have to justify a /8, /15, /16, and /24.  I'm  
just pointing out the number of students alone clearly doesn't justify  
their IP space.

UCLA, where the Internet was invented, only has 5x/16 + 2x/24.   
Obviously they're so much smarter they can utilize IP space better.   
(No, I'm not saying that just 'cause I went to UCLA. :)
