NAME

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

SYNOPSIS

9           use Net::DNS;
10           $rr = Net::DNS::RR->new( '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   match
46           $matched = $rr->match( 'example.foo' );
47
48       match() returns a Boolean true value if the canonical form of the name
49       argument matches the canonical owner name of the NSEC RR.
50
51   covers
52           $covered = $rr->covers( 'example.foo' );
53
54       covers() returns a Boolean true value if the canonical form of the
55       name, or one of its ancestors, falls between the owner name and the
56       nxtdname field of the NSEC record.
57
58   encloser, nextcloser, wildcard
59           $encloser = $rr->encloser( 'example.foo' );
60           print "encloser: $encloser\n" if $encloser;
61
62       encloser() returns the name of a provable encloser of the query name
63       argument obtained from the NSEC RR.
64
65       nextcloser() returns the next closer name, which is one label longer
66       than the closest encloser.  This is only valid after encloser() has
67       returned a valid domain name.
68
69       wildcard() returns the unexpanded wildcard name from which the next
70       closer name was possibly synthesised.  This is only valid after
71       encloser() has returned a valid domain name.
