Agreed. :) You don't really want 10,000 entries in a routing FIB table either, but I was seriously encouraged by the work going on in linux 4.0 and 4.1 to improve those lookups.
One obvious way to deal with that is to put some manageable number of hosts on a subnet and route traffic between the subnets. I think we can assume they'll all have 10/8 addresses, and I'm not too worried about performance to the outside world, just within the network. R's, John
