NAME
Net::DNS::RR::NSEC - DNS NSEC resource record
SYNOPSIS
use Net::DNS;
$rr = Net::DNS::RR->new( 'name NSEC nxtdname typelist' );
DESCRIPTION
Class for DNSSEC NSEC 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.
nxtdname
$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
@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.
typemap
$exists = $rr->typemap($rrtype);
typemap() returns a Boolean true value if the specified RRtype occurs
in the type bitmap of the NSEC record.
match
$matched = $rr->match( 'example.foo' );
match() returns a Boolean true value if the canonical form of the name
argument matches the canonical owner name of the NSEC RR.
covers
$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.
encloser, nextcloser, wildcard
$encloser = $rr->encloser( 'example.foo' );
print "encloser: $encloser\n" if $encloser;
encloser() returns the name of a provable encloser of the query name
argument obtained from the NSEC RR.
nextcloser() returns the next closer name, which is one label longer
than the closest encloser. This is only valid after encloser() has
returned a valid domain name.
wildcard() returns the unexpanded wildcard name from which the next
closer name was possibly synthesised. This is only valid after
encloser() has returned a valid domain name.
