<p>Methods and systems analyze historical NXD traffic to predict future DNS traffic. In one embodiment, a system may count NXD responses generated by an Authoritative DNS server during a particular time period and calculate the variance in NXD traffic for domains over time. The system may then generate a coefficient of variance (CoV) value for each domain observed. Finally, the system may predict positive domain traffic based upon the calculated CoV data. In other embodiments, the system may also base the prediction on the classification of domains as "original" domains or "re-registered" domains. In another embodiment, the system may also base the prediction on the "size" of name servers. Additionally, or alternatively, the system may determine the number of unique name servers for a domain and base the prediction on the number of unique name servers for a particular domain name.</p> |
