What type of DNS lookup method would you use if you want to find the IP address but only receive partial answers?

The appropriate method to use when you want to find an IP address but only receive partial answers is the iterative lookup. In an iterative DNS lookup, the DNS resolver queries a series of DNS servers, receiving responses that may include partial answers or referrals to other DNS servers. This method allows the resolver to progressively gather information until it reaches the authoritative server for the requested domain, which provides the final answer.

This process is beneficial when the initial server does not have the complete answer but can direct the resolver to other servers that might. The iterative lookup contrasts with a recursive lookup, where the resolver takes on the responsibility of following referrals until it finds the answer, often resulting in complete answers delivered back to the original requester without partial results. Caching lookup refers to responses that are stored locally to expedite future requests and does not involve seeking out additional information. A forward lookup specifically refers to the process of finding an IP address from a domain name, but does not indicate the nature of the responses (partial or complete) received during the process.
