Abstract
The present application describes systems and methods for populating a DNS cache of a recursive DNS server using information gathered by a threat intelligence system. The threat intelligence system may collect some or all DNS responses from one or more recursive DNS servers as the one or more DNS servers process various received requests. Since the threat intelligence engine has access to this DNS data, the DNS data may be used to seed a DNS cache of a recursive DNS server.
