Recursive DNS Resolution

Recursive DNS resolution is a DNS lookup strategy where the queried DNS server takes responsibility for resolving the full domain name on behalf of the client. The client sends one query and expects a final answer, such as an A record containing the IP address.

$$\text{Host}\to \text{Local DNS Resolver}$$

The resolver then performs the remaining DNS queries internally and finally returns the resolved result to the host.
