Abstract: In an example, there is provided a method for tracking domain name server (DNS) requests, wherein the method comprises determining whether a DNS request has resolved; and for each non-resolving DNS request decomposing the domain name of the request into multiple components, determining, for each component, a value of a metric representing the occurrence of the component in a corpus, generating a scaling factor for the request on the basis of the values for each component, and incrementing a count of the total number of non-resolving DNS requests by a scaled value on the basis of the scaling factor.
