How many students does MIT have again?

<quote> MIT enrolls more graduate students (approximately 6,000 in total) than undergraduates (approximately 4,000). </quote> 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. :) -- TTFN, patrick * 18.0.0.0 * 128.30.0.0/15 * 128.52.0.0 * 192.233.33.0
legacy class A address space just isn't that big...There is more legacy space (IANA_Registry + VARIOUS, using Geoff's labels) than all space allocated by the RIRs combined.
