In classful addressing, class A networks would allow up to 16,777,214 hosts be attached to the network. In reality, how was this managed? This many hosts were attached to a single LAN? Was the traffic so light that this many hosts could be attached? Were there no routers used to break up collision domains? As I understand, any bridging employed would only compartmentalize broadcasts.
Any insight which can be shared would be appreciated as this seems to be an unreal number of hosts to have on a single segment.
