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

SYNOPSIS
        use Net::DNS;
        $rr = Net::DNS::RR->new('name HTTPS SvcPriority TargetName SvcParams');

DESCRIPTION
    DNS Service Binding (SVCB) resource record

    Service binding and parameter specification via the DNS (SVCB and HTTPS
    RRs)

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.

  SvcPriority
        $svcpriority = $rr->svcpriority;
        $rr->svcpriority( $svcpriority );

    The priority of this record (relative to others, with lower values
    preferred). A value of 0 indicates AliasMode.

  TargetName
        $rr->targetname( $targetname );
        $effecivetarget = $rr->targetname;

    The domain name of either the alias target (for AliasMode) or the
    alternative endpoint (for ServiceMode).

    For AliasMode SVCB RRs, a TargetName of "." indicates that the service
    is not available or does not exist.

    For ServiceMode SVCB RRs, a TargetName of "." indicates that the owner
    name of this record must be used as the effective TargetName.

  mandatory, alpn, no-default-alpn, port, ipv4hint, ech, ipv6hint
        $rr = Net::DNS::RR->new( 'svcb.example. SVCB 1 svcb.example. port=1234' );

        $rr->port(1234);
        $string = $rr->port();      # \004\210
        $rr->key3($string);

    Constructor methods for mnemonic SvcParams defined in
    draft-ietf-dnsop-svcb-https. When invoked without arguments, the methods
    return the presentation format value for the underlying key. The
    behaviour with undefined arguments is not specified.

  keyNN
        $keynn = $rr->keyNN;
        $rr->keyNN( $keynn );
        $rr->keyNN( undef );

    Generic constructor and accessor methods for SvcParams. The key index NN
    is a decimal integer in the range 0 .. 65535. The method argument and
    returned value are both presentation format strings. The method returns
    the undefined value if the key is not present. The specified key will be
    deleted if the value is undefined.
