Abstract: A computer-implemented method is presented for scanning a computer network. The method includes: a) sending a particular network probe to a network address in a computer network; b) receiving a response to the network probe from the network address; c) appending the response to a set of features forming a feature vector; d) determining a next network probe to conduct at the network address; and e) predicting, by the computer processor, the response from the next network probe using the feature vector and a model, where the model is trained using a machine learning method and outputs a probability that a given network address will respond to a network probe.
