NAME

6       Net::DNS::RR::NSEC3 - DNS NSEC3 resource record
7

SYNOPSIS

9           use Net::DNS;
10           $rr = new Net::DNS::RR('name NSEC3 algorithm flags iterations salt hnxtname');

DESCRIPTION

13       Class for DNSSEC NSEC3 resource records.
14
15       The NSEC3 Resource Record (RR) provides authenticated denial of
16       existence for DNS Resource Record Sets.
17
18       The NSEC3 RR lists RR types present at the original owner name of the
19       NSEC3 RR.  It includes the next hashed owner name in the hash order of
20       the zone.  The complete set of NSEC3 RRs in a zone indicates which
21       RRSets exist for the original owner name of the RR and form a chain of
22       hashed owner names in the zone.
23

METHODS

25       The available methods are those inherited from the base class augmented
26       by the type-specific methods defined in this package.
27
28       Use of undocumented package features or direct access to internal data
29       structures is discouraged and could result in program termination or
30       other unpredictable behaviour.
31
32   algorithm
33           $algorithm = $rr->algorithm;
34           $rr->algorithm( $algorithm );
35
36       The Hash Algorithm field is represented as an unsigned decimal integer.
37       The value has a maximum of 255.
38
39       algorithm() may also be invoked as a class method or simple function to
40       perform mnemonic and numeric code translation.
41
42   flags
43           $flags = $rr->flags;
44           $rr->flags( $flags );
45
46       The Flags field is represented as an unsigned decimal integer.  The
47       value has a maximum value of 255.
48
49       optout
50            $rr->optout(1);
51
52            if ( $rr->optout ) {
53                   ...
54            }
55
56           Boolean Opt Out flag.
57
58   iterations
59           $iterations = $rr->iterations;
60           $rr->iterations( $iterations );
61
62       The Iterations field is represented as an unsigned decimal integer.
63       The value is between 0 and 65535, inclusive.
64
65   salt
66           $salt = $rr->salt;
67           $rr->salt( $salt );
68
69       The Salt field is represented as a contiguous sequence of hexadecimal
70       digits. A "-" (unquoted) is used in string format to indicate that the
71       salt field is absent.
72
73   saltbin
74           $saltbin = $rr->saltbin;
75           $rr->saltbin( $saltbin );
76
77       The Salt field as a sequence of octets.
78
79   hnxtname
80           $hnxtname = $rr->hnxtname;
81           $rr->hnxtname( $hnxtname );
82
83       The Next Hashed Owner Name field points to the next node that has
84       authoritative data or contains a delegation point NS RRset.
85
86   typelist
87           @typelist = $rr->typelist;
88           $typelist = $rr->typelist;
89           $rr->typelist( @typelist );
90
91       The Type List identifies the RRset types that exist at the domain name
92       matched by the NSEC3 RR.  When called in scalar context, the list is
93       interpolated into a string.
94
95   covered, match
96           print "covered" if $rr->covered{'example.foo'}
97
98       covered() returns a nonzero value when the the domain name provided as
99       argument is covered as defined in the NSEC3 specification:
100
101          To cover:  An NSEC3 RR is said to "cover" a name if the hash of the
102             name or "next closer" name falls between the owner name and the
103             next hashed owner name of the NSEC3.  In other words, if it proves
104             the nonexistence of the name, either directly or by proving the
105             nonexistence of an ancestor of the name.
106
107       Similarly matched() returns a nonzero value when the domainname in the
108       argument matches as defined in the NSEC3 specification:
109
110          To match: An NSEC3 RR is said to "match" a name if the owner name
111             of the NSEC3 RR is the same as the hashed owner name of that
112             name.
