Lame Delegation or response occurs when the Resolution of the Query indicates that the Responder is not the Authoritative name server of the required zone. This means that the server responding is not the correct server to provide the information requested, leading to potential inaccuracies or delays in resolving the query.
Additionally, Lame Delegation can also occur when the server responds with delays or does not respond at all, further complicating the resolution process.
