1. A method for identifying devices on a network, comprising:
determining, by a discovery application executing on a computer, a prioritized discovery plan including a plurality of tiers of requests, each of the tiers specifying one or more probes for targeting specific types of devices, wherein the prioritized discovery plan further comprises transmission settings;
for each of the tiers in the prioritized discovery plan:
causing, by the discovery application, one or more of the probes specified for the tier to transmit targeted requests to a set of active addresses on the network;
upon receiving responses from at least a subset of the one or more addresses, identifying, by the discovery application, one or more devices connected to the network based on the responses to the targeted requests; and
removing, by the discovery application, addresses corresponding to the identified one or more devices from the set of active addresses on the network.
