2.4.3. RRset Does Not Exist

No RRs with a specified NAME and TYPE (in the zone and class denoted by the Zone Section) can exist.

For this prerequisite, a requestor adds to the section a single RR whose NAME and TYPE are equal to that of the RRset whose nonexistence is required. The RDLENGTH of this record is zero (0), and RDATA field is therefore empty. CLASS must be specified as NONE in order to distinguish this condition from a valid RR whose RDLENGTH is naturally zero (0) (for example, the NULL RR). TTL must be specified as zero (0).
