NAME

6       Net::DNS::RR::NSEC - DNS NSEC resource record
7

SYNOPSIS

9           use Net::DNS;
10           $rr = new Net::DNS::RR( 'name NSEC nxtdname typelist' );
11

DESCRIPTION

13       Class for DNSSEC NSEC resource records.
14

METHODS

16       The available methods are those inherited from the base class augmented
17       by the type-specific methods defined in this package.
18
19       Use of undocumented package features or direct access to internal data
20       structures is discouraged and could result in program termination or
21       other unpredictable behaviour.
22
23   nxtdname
24           $nxtdname = $rr->nxtdname;
25           $rr->nxtdname( $nxtdname );
26
27       The Next Domain field contains the next owner name (in the canonical
28       ordering of the zone) that has authoritative data or contains a
29       delegation point NS RRset.
30
31   typelist
32           @typelist = $rr->typelist;
33           $typelist = $rr->typelist;
34
35       typelist() identifies the RRset types that exist at the NSEC RR owner
36       name.  When called in scalar context, the list is interpolated into a
37       string.
38
39   typemap
40           $exists = $rr->typemap($rrtype);
41
42       typemap() returns a Boolean true value if the specified RRtype occurs
43       in the type bitmap of the NSEC record.
44
45   covers
46           $covered = $rr->covers( 'example.foo' );
47
48       covers() returns a Boolean true value if the canonical form of the
49       name, or one of its ancestors, falls between the owner name and the
50       nxtdname field of the NSEC record.
