Abstract:
Techniques are disclosed for classifying a network flow based on a domain name system (DNS) request. Embodiments receive a first DNS request associated with establishing a network flow with a remote service. Here, the first DNS request specifies a domain name associated with the remote service. The domain name is analyzed in order to determine a first classification for the remote service. The first classification is selected from a plurality of classifications. Embodiments then determine a network management policy to apply to the network flow, based on the determined first classification.
