Deletes an entire rrset

RFC 2136, DNS Update, April 1997

2.5.2 - Delete An RRset

  One RR is added to the Update Section whose NAME and TYPE are those
  of the RRset to be deleted.  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 RRset exists, then this Update RR will be silently ignored
  by the Primary Zone Server.

ยงArguments

  • record - The name, class and record_type will be used to match and delete the RecordSet
  • zone_origin - the zone name to update, i.e. SOA name
  • 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). If no such RRset exists, then this Update RR will be silently ignored by the Primary Zone Server.
