BIND Plugin

Our goal is to replace our current DNS infrastructure with a dynamic split-horizon DNS. For that we need a bind module ( implemented like the DLZ is ) that wil will execute the following logic: For the flow of the plugin please check the attached image. The deliverable needs to be a patch that can be applied to the latest stable BIND ( 9.10.1 ) and that does not change the way bind works in any way or form except the specified scenario. The deliverable will be a plugin and not a patch to the way bind runs. Proposed db: domains: id: int domain: varchar ns1: varchar ns2: varchar domain_class: id: int domain_id: FK to domains->id ip_class: varchar ( of ip classes allowed: eg: [login to view URL] ) mappins: id: int domain_id: FK to domains->id from: varchar ( eg [login to view URL] ) to: varchar ( eg [login to view URL], so when a request comes in and the ns for the domain will return [login to view URL], we will change that to [login to view URL] )
