NODATA

[Watanabe, Hiroshi]

Hi Kevin,
Thank you for your reply.

I could get NODATA with SRV record. (I'm using BIND8.2.2-p5)
But if I remove A record and query, I couldn't find NODATA of A record
on memory.
How can I get the NODATA with A record.

Thanks
Hiroshi

Pick a name. Query for that name, with a record type that you know the
name doesn't own. For instance, if you know you have no HINFO records
for a particular name that "exists" (i.e. it owns records of some
*other* type(s)), query the name with record type HINFO. You should get
a response with RCODE=3DNOERROR, 0 answers and no referral records in =
the
Authority Section, i.e. what is commonly known as a NODATA response.=20
Modern versions of BIND will know to cache such "negative" responses.=20
See RFC 2308 for more details.
