Given your MIT connections, you should be able to approach Akamai for an 
educational license to their IP data base also known as EdgeScape db.

Out of personal experience, I can tell you it is pretty darn good. Here 
is a sample of some of the fields you can get given an IP address 
(effectively a CIDR block):

Country, State (US), City, Phone Area Code, Country, Latitude, 
Longitude, Time Zone, Network Type (Dialup/DSL/Cable)

Also for US it gives:

DMA: Designated Marketing Areas
MSA: Metropolitan Statistical Areas
PMSA: Primary Metropolitan Statistical Areas
