This can be used to indicate, for example, that an attempt was made by dns_query() to make a query, but the name server (e.g. a DNS server) replied indicating that it had no matching records. Would this be the same as NXDOMAIN? That is, does it mean the name server couldn't find a record, or does it mean that the record doesn't exist?
