Deletes all rrsets at the specified name

RFC 2136, DNS Update, April 1997

2.5.3 - Delete All RRsets From A Name

  One RR is added to the Update Section whose NAME is that of the name
  to be cleansed of RRsets.  TYPE must be specified as ANY.  TTL must
  be specified as zero (0) and is otherwise not used by the Primary
  Zone Server.  CLASS must be specified as ANY.  RDLENGTH must be zero (0)
  and RDATA must therefore be empty.  If no such RRsets exist, then
  this Update RR will be silently ignored by the Primary Zone Server.

ยงArguments

  • name_of_records - the name of all the record sets to delete
  • zone_origin - the zone name to update, i.e. SOA name
  • dns_class - the class of the SOA
  • use_edns - if true, EDNS options will be added to the request

The update must go to a zone authority (i.e. the server used in the ClientConnection). This operation attempts to delete all resource record sets at the specified name, regardless of the record type.
