Techniques for performing flow-based host discovery in an SDN network are provided. According to one embodiment, an SDN controller can select, based on network topology information that is stored on the controller, a leaf network device in the network, and can determine a traffic flow corresponding to a flow rule installed on the leaf network device. The determining of the traffic flow can be based on flow rule information that is stored on the SDN controller. The SDN controller can further determine a forward path for the traffic flow through the network, where the determining of the forward path is performed by associating the flow rule with other flow rules for the traffic flow that are included in the flow rule information, and where the other flow rules are installed on other network devices in the network. The SDN controller can then determine, based on at least the forward path, host information for the source and destination hosts of the traffic flow.
