- Domain Name Service - Recursion
The great DNS recursion process. The client will first check the cache, if it is unable to find its resolution there, it will send the query to its primary DNS server. The DNS server will then check its cache and zone records. If it is unable to resolve the client's query there it will pursue attempts at conditional forwarding, then Stub Zones. If the primary DNS server is still unable to resolve the request, it will utilize root hints and delegation to provide FQDN resolution.
