# Net::DNS::RR::CSYNC - phpMan

## NAME
    [Net::DNS::RR::CSYNC] - DNS CSYNC resource record

## SYNOPSIS
        use [Net::DNS];
        $rr = [Net::DNS::RR]->new('name CSYNC SOAserial flags typelist');

## DESCRIPTION
    Class for DNSSEC CSYNC resource records.

## METHODS
    The available methods are those inherited from the base class augmented
    by the type-specific methods defined in this package.

    Use of undocumented package features or direct access to internal data
    structures is discouraged and could result in program termination or
    other unpredictable behaviour.

  SOAserial
  soaserial
        $soaserial = $rr->soaserial;
        $rr->soaserial( $soaserial );

    The SOA Serial field contains a copy of the 32-bit SOA serial number
    from the child zone.

  flags
        $flags = $rr->flags;
        $rr->flags( $flags );

    The flags field contains 16 bits of boolean flags that define operations
    which affect the processing of the CSYNC record.

    immediate
         $rr->[immediate(1)];

         if ( $rr->immediate ) {
                ...
         }

        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.

    soaminimum
         $rr->[soaminimum(1)];

         if ( $rr->soaminimum ) {
                ...
         }

        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.

  typelist
        @typelist = $rr->typelist;
        $typelist = $rr->typelist;

    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.
