Thanks for your useful remarks Doug.

For those wishing to examine DHCP and IP number management on Ethernets
from both a technical and administrative perspective check out:

http://ltpwww.gsfc.nasa.gov:81/ltpcf/

This is by far the best single source of information on the subject I've
discovered.

As we add more and more commercial sites to our backbone, we are being
asked to help these sites manage their IP number usage.

This question was raised by several schools in our area. They would like to 
place 500-1000 computers on the net, but understand the need to manage IP
namespace. Most of these systems are not in use simultaneously. 

How do Universities manage their IP namespace? Dedicated IP ? IP lease? What 
is U0 going to use to manage the numbers?
