The 2 standard approaches to working with this issue are "recursive", wherein the main server pursues the question for that customer at A further server, and "iterative", by which the server refers the customer to another server and allows the consumer pursue the query. each techniques have advantages and drawbacks, although the iterative approach is desired to the datagram form of accessibility. The domain procedure needs implementation in the iterative method, but permits the recursive solution as an alternative. Mockapetris [webpage 4]
