Net::DNS::RR::NSEC - DNS NSEC resource record
$rr = new Net::DNS::RR( 'name NSEC nxtdname typelist' );
Class for DNSSEC NSEC
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.
$nxtdname = $rr->nxtdname;
$rr->nxtdname( $nxtdname );
The Next Domain field contains the next owner name (in the
canonical ordering of the zone) that has authoritative data
or contains a delegation point NS RRset.
@typelist = $rr->typelist;
$typelist = $rr->typelist;
typelist() identifies the RRset types that exist at the NSEC RR
owner name. When called in scalar context, the list is interpolated
into a string.
$exists = $rr->typemap($rrtype);
typemap() returns a Boolean true value if the specified RRtype occurs
in the type bitmap of the NSEC record.
$covered = $rr->covers( 'example.foo' );
covers() returns a Boolean true value if the canonical form of the name,
or one of its ancestors, falls between the owner name and the nxtdname
field of the NSEC record.
