Here's the problem: We have out grown our present configuration for IP networking. We have a half dozen or so C class networks (not registered), one of which is filling rapidly. We will soon be attaching to Internet and will be using one B class number (registered) for the whole campus. We would like to split the B into different sized subnets say of sizes to support 2 (host-host), 14, 62, 254, 2046 hosts. On NIC's suggestion, we will use all 1s on a given net for broadcast and reserve all 0s on a given net. There will be at least one gateway to the outside Internet. What did you do?
