Abstract
Systems and methods for analyzing domain name system (“DNS”) lookup data perform operations that may include: calculating traffic scores for a network address based on a set of DNS lookup data associated with the network address, where the set of DNS lookup data includes a plurality of query records having one or more queried network addresses; calculating a first variance and a second variance for the network address based on the traffic scores for the network address; and determining a rank of the network address based on the first and second variances.
