Would someone mind explaining how it knows what region each IP address
should be in?  I'm guessing it's just something simple, like having the
top-level mirrors point different places in different regions, so it
depends who you peer off of?

I just find the following results odd:
 69.212.*.*  Residential DSL connection --> america
130.126.*.*  University                 --> other
128.174.*.*  Same University            --> other
131.225.*.*  US National Lab            --> other
