I think you may be confusing the time scales for "proactive" and "reactive". Most people use them to mean "before or after the first packet in a flow", but if you want to, for example, upon seeing an ARP from host X, proactively install flow rules that match all possible traffic to host X, then this is a fairly viable strategy. Additionally, if your hosts are VMs and you're using an orchestration system, you don't even necessarily have to wait for an ARP as the orchestration system will tell you where the hosts are located, so in this case, you're "reacting" to host moves in the orchestration system.
Hope this helps, - Rob .
