The 0.0.0.0/8 is new to me..what is its purpose? It's a reserved, unassigned network. I don't have an RFC handy to check, but I believe that the reasoning might have been because of the "magic" "address" 0.0.0.0 that it contains. It seems simpler to lose it than to be in doubt, and I think I saw a detailed argument at one point, anyways... ;-) ...
