The named server received a response from a named server at ip_address while attempting to resolve the name, dns_name in the domain, domain_name. The parent named server of the domain_name named server incorrectly delegated the domain_name domain to the named server at ip_address, and the named server at ip_address is not authoritative for the domain, domain_name. That server is termed a 'lame server' because of the misconfiguration.

dns_name is the name that was being resolved by the named server.

domain_name is the domain name that was incorrectly delegated.

ip_address is the address of the named server that is not actually authoritative for domain_name, but is believed to be authoritative by the named server that is authoritative for domain_name's parent domain.
