Abstract
A Domain Name System (“DNS”) package, a non-transitory computer-readable medium, and a method for providing domain name resolution services are disclosed. The system can include one or more built-in DNS hierarchy databases configured for deployment within a network, wherein the one or more built-in DNS hierarchy databases stores DNS records. The system can also include a recursive name server, wherein the recursive name server is configured to query the one or more built-in DNS hierarchy databases during domain name resolution, the recursive name server configured to select the one or more built-in DNS hierarchy databases based on a policy indicating a preference for the one or more built-in DNS hierarchy databases over a domain name server located outside of the network. Furthermore, the system can include a recursive name server database configured to store DNS records for the recursive name server.
