Recursive Lookup

Recursive lookup is a process where a system, such as a computer network or software, handles a request by repeatedly asking additional sources until it finds the needed information. For example, when resolving a website's address, the system checks local records first. If not found, it asks higher-level sources, which may in turn ask others, continuing until the address is identified. This step-by-step approach ensures that complex or layered information is traced through multiple sources efficiently, ultimately providing the correct data needed for the user or system to proceed.
