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.
