.SH NAME
Net::DNS::RR::CSYNC \- DNS CSYNC resource record
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&    use Net::DNS;
\&    $rr = Net::DNS::RR\->new(\*(Aqname CSYNC SOAserial flags typelist\*(Aq);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Class for DNSSEC CSYNC resource records.
.SH METHODS
.IX Header "METHODS"
The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.
.PP
Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.
.SS SOAserial
.IX Subsection "SOAserial"
.SS soaserial
.IX Subsection "soaserial"
.Vb 2
\&    $soaserial = $rr\->soaserial;
\&    $rr\->soaserial( $soaserial );
.Ve
.PP
The SOA Serial field contains a copy of the 32\-bit SOA serial number from
the child zone.
.SS flags
.IX Subsection "flags"
.Vb 2
\&    $flags = $rr\->flags;
\&    $rr\->flags( $flags );
.Ve
.PP
The flags field contains 16 bits of boolean flags that define operations
which affect the processing of the CSYNC record.
.IP immediate 4
.IX Item "immediate"
.Vb 1
\& $rr\->immediate(1);
\&
\& if ( $rr\->immediate ) {
\&        ...
\& }
.Ve
.Sp
If not set, a parental agent must not process the CSYNC record until
the zone administrator approves the operation through an out-of-band
mechanism.
.IP soaminimum 4
.IX Item "soaminimum"
.Vb 1
\& $rr\->soaminimum(1);
\&
\& if ( $rr\->soaminimum ) {
\&        ...
\& }
.Ve
.Sp
If set, a parental agent querying child authoritative servers must not
act on data from zones advertising an SOA serial number less than the
SOAserial value.
.SS typelist
.IX Subsection "typelist"
.Vb 2
\&    @typelist = $rr\->typelist;
\&    $typelist = $rr\->typelist;
.Ve
.PP
The type list indicates the record types to be processed by the parental
agent. When called in scalar context, the list is interpolated into a
string.
