nsupdate: using "wildcard" TTL when removing specific record

[Petr Bena]

Hello,

Is there any way to tell nsupdate to delete specific record with ANY TTL
value? For example I have following record:

record.domain.org 3500 A 1.2.3.4

I want to delete exactly that record (A with IP 1.2.3.4), except I don't
know what the TTL is, normally, if I knew the TTL, I would do

update delete record.domain.org 3500 A 1.2.3.4

But I would like to do something like

update delete record.domain.org * A 1.2.3.4

Is there any way to accomplish this, or do I always have to retrieve the
record somehow, figure out the TTL and then continue?

Thanks

TTL is ignored on delete if it present. It is set to 0 when sending.

2.5.4 - Delete An RR From An RRset

RRs to be deleted are added to the Update Section. The NAME, TYPE,
RDLENGTH and RDATA must match the RR being deleted. TTL must be
specified as zero (0) and will otherwise be ignored by the primary
master. CLASS must be specified as NONE to distinguish this from an
RR addition. If no such RRs exist, then this Update RR will be
silently ignored by the primary master.
