Slides from the Techlink presentation "What is this CAM domain thing anyway?" given by Bob Franklin and Jon Warbrick, February 2008.
WARNING: while these slides remain basically correct, details of the way that the CUDN works have changed since 2008. In particular the address ranges in use continue to change, rendering many of the examples in the slides misleading. See http://www.cam.ac.uk/cs/network/ip/camnets.html for the definitive reference.
