NAME
    Net::DNS::RR::NSEC3 - DNS NSEC3 resource record

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

DESCRIPTION
    Class for DNSSEC NSEC3 resource records.

    The NSEC3 Resource Record (RR) provides authenticated denial of
    existence for DNS Resource Record Sets.

    The NSEC3 RR lists RR types present at the original owner name of the
    NSEC3 RR. It includes the next hashed owner name in the hash order of
    the zone. The complete set of NSEC3 RRs in a zone indicates which RRSets
    exist for the original owner name of the RR and form a chain of hashed
    owner names in the zone.

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.

  algorithm
        $algorithm = $rr->algorithm;
        $rr->algorithm( $algorithm );

    The Hash Algorithm field is represented as an unsigned decimal integer.
    The value has a maximum of 255.

    algorithm() may also be invoked as a class method or simple function to
    perform mnemonic and numeric code translation.

  flags
        $flags = $rr->flags;
        $rr->flags( $flags );

    The Flags field is an unsigned decimal integer interpreted as eight
    concatenated Boolean values.

    optout
         $rr->optout(1);

         if ( $rr->optout ) {
                ...
         }

        Boolean Opt Out flag.

  iterations
        $iterations = $rr->iterations;
        $rr->iterations( $iterations );

    The Iterations field is represented as an unsigned decimal integer. The
    value is between 0 and 65535, inclusive.

  salt
        $salt = $rr->salt;
        $rr->salt( $salt );

    The Salt field is represented as a contiguous sequence of hexadecimal
    digits. A "-" (unquoted) is used in string format to indicate that the
    salt field is absent.

  saltbin
        $saltbin = $rr->saltbin;
        $rr->saltbin( $saltbin );

    The Salt field as a sequence of octets.

  hnxtname
        $hnxtname = $rr->hnxtname;
        $rr->hnxtname( $hnxtname );

    The Next Hashed Owner Name field points to the next node that has
    authoritative data or contains a delegation point NS RRset.

  typelist
        @typelist = $rr->typelist;
        $typelist = $rr->typelist;
        $rr->typelist( @typelist );

    typelist() identifies the RRset types that exist at the domain name
    matched by the NSEC3 RR. 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 NSEC3 record.

  match
        $matched = $rr->match( 'example.foo' );

    match() returns a Boolean true value if the hash of the domain name
    argument matches the hashed owner name of the NSEC3 RR.

  covers
        $covered = $rr->covers( 'example.foo' );

    covers() returns a Boolean true value if the hash of the domain name
    argument, or ancestor of that name, falls between the owner name and the
    next hashed owner name of the NSEC3 RR.

  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 NSEC3 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.
