Define ENAMEUNKNOWN to indicate "Network name unknown". 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?
Is there a way to tell the difference? Can you store a negative record in the
DNS? Or is it that the DNS has records for the name, just not records of the
type you're looking for (eg. NO_ADDRESS/NO_DATA from gethostbyname())?
