MSU also has a full class A, so there are only 127 other possible IPv4
holders in the same class.  Most locations do NOT have the ability to
use static IP addresses for everything, let alone full subnets.  Most
countries (and I think even some continents) have less total IPv4
addresses available than MSU does.  Many universities, for example, only
have one or a few scattered class C ranges available for the entire
organization and its affiliates.  MSU IP address assignments like this
are very wasteful of public address space and not viable solutions for
the community at large.  Also, universities will often use address space
they don't own (for example, through Merit) which may or may not be
shared with others.
