DNS Basic Name Resolution Techniques: Iterative and Recursive Resolution (Page 3 of 4) Recursive Resolution When a client sends a recursive request to a name server, the server responds back with the answer if it has the information sought. If it doesn't, the server takes responsibility for finding the answer by becoming a client on behalf of the original client and sending new requests to other servers. The original client only sends one request, and eventually gets the information it wants (or an error message if it is not available). This technique is shown in Figure 244.
